The `rag query` command can be slow due to the "super-rerank" mode. When this mode is enabled, the AI reviews more chunks of information before answering your question. This additional processing time can lead to slower responses, but it aims to provide a more accurate and better-quality result. You can enable or disable this mode using the `--super-rerank` or `--no-super-rerank` argument in the command.

The `rag query` command can experience slowness due to several factors, which may include:

1. **Model Performance**: The default model you are using may impact speed. For example, models like `gpt-4o-mini` or `llama3.3-70b-groq` might have different performance characteristics. You may want to consider switching models if you find one is slower.

2. **Token Count**: The number of input and output tokens can also affect processing time. If the query generates a large token count or takes a long time to process the input, it can slow down the response from the model.

3. **Knowledge-Base Size**: Queries against a larger knowledge-base may take more time to search and retrieve relevant information, especially if the database isn't optimized or indexed properly.

4. **API Calls**: If you're using a proprietary API to run your queries, the latency in network calls could also result in increased query times, especially if the service is experiencing high traffic.

5. **System Resources**: The performance of the local machine or server where the command is being run can also impact speed, particularly if system resources (CPU, memory) are constrained.

6. **Configuration Settings**: Depending on your configuration settings, particularly those related to processing and token limits, you may be able to optimize performance.

To diagnose and improve performance, you can enable detailed logs by running `rag config --set dump_log true`, which can help you identify what might be causing the delay. You may want to experiment with different configurations or models to find an optimal setup for your needs.

Short answer: rag query can be slow because it does several LLM-driven steps, and some modes/configs add even more.

Where the time goes
- Normal mode runs multiple LLM calls:
  1) Extract keywords from your query
  2) Rerank the tfidf candidates
  3) Generate the final answer
  Increasing max_summaries (more candidates to consider) or max_retrieval (more chunks to rerank/use) makes steps 2 and 3 heavier and slower.
- Interactive multi-turn: before running the pipeline, it first rewrites your follow‑up into a context-rich query (another LLM call), then does the same steps as normal mode.
- Agent mode: the agent “browses files and tries to answer your question.” That triggers many tool/LLM calls and is explicitly the “most expensive” path, so it’s the slowest.

How to make it faster
- Prefer normal mode for simple questions; avoid --agent unless you truly need it.
- Reduce work per query:
  - Lower max_summaries
  - Lower max_retrieval
  - Disable super rerank if it’s enabled (--no-super-rerank)
- Use a faster model via --model (or set a faster default in config.model).
- If you only need follow‑ups occasionally, consider issuing a fresh normal query instead of interactive multi‑turn to skip the rewrite step.
- To see where time is spent, try:
  - rag extract-keywords <q> (tests the keyword-extraction LLM step)
  - rag retrieve-chunks <q> (runs the retrieval + rerank steps without final answer)

In short, latency scales with the number of LLM calls and how much text those calls must read and score. Modes like interactive multi‑turn and agent add extra steps; higher retrieval settings make each step heavier.

----- model: gpt-5-mini -----
-- query (47.53s) --
Short answer: because rag query is a multi-step pipeline that often makes several expensive LLM calls and extra work (and agent mode does even more). Other causes are large retrieval settings or a missing/dirty inverted-index which make the search and rerank steps slower.

Why it’s slow (details)
- Multiple LLM passes in the pipeline:
  - Step 2: an LLM extracts search keywords from your query.
  - Step 4: an LLM reranks the top-N tfidf hits (reviews titles/summaries).
  - Step 5: an LLM generates the final RAG answer.
  Those are separate model calls and each adds latency/cost.
- Agent mode is much heavier: the agent browses files/chunks and runs more LLM work. Release notes explicitly say agent mode is “almost always more expensive and time-consuming than non-agent mode.”
- Large retrieval/summarization settings: high max_summaries or max_retrieval means more chunks to fetch/rerank, increasing work and extra LLM calls.
- Inverted-index issues: if the inverted index is missing or dirty (e.g., after rag remove), tfidf search can be slower. The code tries to auto-build the II now, but sometimes you must rebuild.
- Extra options that trigger more LLM work: features like “super-rerank” will incur additional expensive passes.
- Model choice / network: using a slow remote model or large model increases latency (and fetching models from remote can add startup time).

How to make it faster (practical tips)
- Avoid agent mode unless necessary: use normal mode for most questions.
- Reduce retrieval work:
  - Lower max_summaries and max_retrieval: e.g. rag config --set max_summaries 5 and rag config --set max_retrieval 3.
- Turn off extra reranking:
  - Disable super-rerank in config or via command (set super_rerank to false).
- Ensure inverted-index is built and healthy:
  - If you suspect the index is dirty, rebuild it: rag build-ii (or run rag build / rag extract-archive which now auto-builds II).
  - After rag remove, run rag build-ii to avoid slow searches.
- Use a faster/smaller model or a local model: change config.model or fetch a faster model with rag model.
- Use the summary cache: rag summary caches summaries; if a cached summary exists, rag query can use it instead of regenerating.
- If you must use an agent, audit costs first: run rag gc --audit and rag audit to inspect cost and behavior.

If you want, tell me:
- whether you’re running with --agent,
- your current max_summaries / max_retrieval and super_rerank settings,
- whether you have an inverted-index built (or whether you recently ran rag remove),
and I’ll give concrete settings/commands to speed up your workflow.

**Short answer**

`rag query` can be slow for a couple of reasons:

1. **The whole “extract‑→search‑→rerank‑→answer” pipeline is LLM‑heavy** – every step that involves the LLM (keyword extraction, reranking, final generation) costs compute time and, if you’re using a remote API, network latency.  
2. **Tfidf‑search on a very large collection can be expensive** – the TF‑IDF engine scans every chunk to compute similarity scores. With thousands of chunks the search phase dominates.  
3. **Configuration defaults can lead to a lot of work** – by default the pipeline retrieves 10 chunks, reranks the top 3, then feeds all that to the LLM again. If you’re on a cheap model or the model is slow, the overhead adds up.  
4. **Extra optional steps (intelligent indexing, super‑rerank, agent mode)** – enabling `--enable-ii`, `--super-rerank`, or running in `--agent` mode pulls in additional data or extra LLM calls, which can make the command feel sluggish.  
5. **Network or API limits** – if you’re hitting rate‑limits or the API endpoint is far away, the latency can be noticeable.

---

## What the pipeline actually does (from *pipeline.md*)

| Step | What happens | Why it can be slow |
|------|--------------|--------------------|
| **1** | User enters query | – |
| **2** | LLM extracts search‑keywords | LLM call – latency + CPU |
| **3** | TF‑IDF search over all stored chunks | Full‑text scan; cost grows with corpus size |
| **4** | LLM reranks the top 10 chunks to pick 3 | Another LLM call (titles + summaries) |
| **5** | LLM generates the answer from the 3 chunks | Final LLM call; the model size matters |

Each LLM call (steps 2, 4, 5) can be the bottleneck, especially if you’re using a large or remote model. The TF‑IDF step is also CPU‑bound when the corpus is huge.

---

## Practical ways to see *why* it’s slow

| Command | What it shows |
|---------|---------------|
| `rag config --set dump_log true` then `rag query …` | Logs for every phase, so you can see how long each step takes. |
| `rag audit` (after enabling `dump_api_usage`) | Token usage & timing for the LLM calls. |
| `rag tfidf` | Test the TF‑IDF search speed separately. |

---

## Things you can tweak to speed it up

| Setting | Default | What happens when you lower it | How to change |
|---------|---------|--------------------------------|---------------|
| `max_summaries` (`--max-summaries`) | 10 | Fewer chunks returned → less work for the LLM reranker and final generator. | `rag config --set max_summaries 5` |
| `max_retrieval` (`--max-retrieval`) | 3 | Fewer chunks fed into the final RAG step → faster generation. | `rag config --set max_retrieval 2` |
| `enable_ii`, `enable_rag`, `super_rerank` | Usually **enabled** by default | Disabling them removes extra LLM calls and indexing work. | `rag query … --disable-ii --disable-rag --no-super-rerank` |
| Use a **smaller model** (`--model`) | The default in `config.model` | Faster inference, lower latency. | `rag query … --model gpt‑3.5‑turbo` |
| **Caching** | No built‑in caching for TF‑IDF or LLM calls | If you’re running the same query repeatedly, cache the TF‑IDF results or the LLM prompt‑output. | Implement a simple in‑memory dict or use `rag gc --cache` if available. |
| **Use the agent mode sparingly** | `--agent` is the most expensive path | Agent mode does a full file‑browse; use only for complex questions. | Stick to normal mode for quick queries. |

---

## TL;DR

- **Why it’s slow?**  
  *Multiple LLM calls (keyword extraction, reranking, final answer) plus a full TF‑IDF scan of every chunk.*  
- **How to confirm?**  
  Enable logs (`rag config --set dump_log true`) or audit (`rag audit`) to see per‑step timings.  
- **How to fix?**  
  Reduce `max_summaries`/`max_retrieval`, disable optional steps (`--disable-ii`, `--disable-rag`, `--no-super-rerank`), use a cheaper model, or tune your corpus size.  

Once you adjust those knobs, most `rag query` invocations become noticeably snappier.

## TL;DR  
`rag query` can feel “terribly slow” for three main reasons:

| Reason | What’s happening under the hood | How to verify it | How to make it faster |
|--------|--------------------------------|------------------|-----------------------|
| **LLM inference latency** | After the retrieval step the command sends a prompt (the retrieved chunks + your question) to the LLM you selected (`--model`). If the model is large, hosted remotely, or the service is under load, the round‑trip can take seconds to minutes. | Turn on API‑usage logging (`rag config --set dump_api_usage true`) and inspect the `.ragit/logs` file – you’ll see the *request‑duration* and token count. | • Use a smaller/faster model (`--model`),<br>• Enable `--disable-ii` or `--disable-rag` if you don’t need the full RAG pipeline, <br>• Cache the model locally if you’re using an open‑source one. |
| **Retrieval & reranking work** | Before the LLM runs, `rag query` pulls **`max_retrieval`** chunks from the vector store (or TF‑IDF engine) and may run a **super‑rerank** step. Pulling many chunks, doing embeddings, or performing an expensive cross‑encoder rerank can dominate the wall‑time. | Look at the JSON log (`--json` or `rag query … --json`) – the `retrieved_chunks` array will show how many items were fetched. If `super_rerank` is on you’ll also see a “rerank” section with its timing. | • Lower `--max-retrieval` and/or `--max-summaries` (e.g. `--max-retrieval 5 --max-summaries 3`).<br>• Disable super‑rerank: `--disable-super-rerank` (or `--no-super-rerank`).<br>• Pre‑compute embeddings or use the lighter TF‑IDF engine (`rag tfidf --query …`). |
| **Agent mode** | `rag query --agent` spawns an autonomous “agent” that browses the filesystem, runs additional sub‑commands, and may invoke several LLM calls. This is the *most expensive* mode. | The command line itself prints “Running in agent mode …”. The logs will contain multiple LLM requests. | • Use normal or interactive mode instead of `--agent` for simple questions.<br>• If you must use the agent, run `rag gc --audit` first and keep the retrieval scope tiny. |

---

## How the docs explain the pieces that cause slowdown  

### 1. The pipeline (from **`rag query` docs**)

* **Normal mode** – runs the *full* pipeline: retrieve chunks → (optional) super‑rerank → build a prompt → call the LLM.  
* **`--interactive`** – same pipeline, but you stay in a REPL.  
* **`--agent`** – “the strongest and the most expensive way”; it may browse files and make *multiple* LLM calls. The docs explicitly warn: *“It’s an overkill to use an agent for a simple question.”*

> **Implication:** If you ever see the command hanging for a long time, check whether you inadvertently ran `--agent` (or an interactive session that continued a previous conversation that fetched many chunks).

### 2. Options that directly affect latency

| Option | Effect on speed |
|--------|-----------------|
| `--max-retrieval <n>` | Controls how many candidate chunks are pulled from the vector store. The default can be large; reducing it shrinks the work. |
| `--max-summaries <n>` | Controls how many of those chunks are summarised and fed to the LLM. Fewer summaries = smaller prompt = faster LLM response. |
| `--enable-ii / --disable-ii` | “II” = *in‑context* retrieval (extra processing). Disabling it skips that step. |
| `--enable-rag / --disable-rag` | Turns the whole retrieval‑augmented generation on/off. Disabling RAG means the LLM works on the raw query only – dramatically faster (but no knowledge‑base grounding). |
| `--[no-]super-rerank` | When enabled, a cross‑encoder re‑scores the retrieved chunks. This is CPU‑/GPU‑heavy. Turning it off (`--no-super-rerank`) removes that cost. |

### 3. Debugging tools (from **`eval.md`**)

* **Log files** – enable them with `rag config --set dump_log true`. Every `rag query` run writes a log under `.ragit/logs`. The timestamps let you see where the time was spent (retrieval vs LLM call vs rerank).  
* **API‑usage logs** – `rag config --set dump_api_usage true` records token counts and request latency for the LLM. Use `rag audit` to see total cost and time.  

> **Tip:** Open the most recent log (`less .ragit/logs/<timestamp>.log`) and search for `retrieval`, `rerank`, and `llm`. The sections are usually clearly marked.

### 4. Comparison with the TF‑IDF command

The **`rag tfidf`** docs remind us that this command *does not* go through the LLM pipeline – it is a pure keyword search. Because it skips embeddings, reranking, and LLM calls, it runs instantly. If you only need a quick keyword lookup, `rag tfidf --query "<your question>"` is a much faster alternative to a full `rag query`.

---

## Practical checklist to diagnose a “slow” query

1. **Check the mode** – Are you using `--agent`? Switch to normal mode.  
2. **Inspect the log** –  
   ```bash
   rag config --set dump_log true
   rag query "my question" > /dev/null   # run the slow command
   tail -n 30 .ragit/logs/*latest*.log   # look for timestamps
   ```
   - If most time is spent in a block labeled *“retrieval”* → reduce `--max-retrieval`.  
   - If most time is in *“super‑rerank”* → add `--no-super-rerank`.  
   - If most time is in *“llm”* → try a smaller model or enable caching.  

3. **Turn off optional heavy features** (quick one‑liner):
   ```bash
   rag query "my question" \
       --max-retrieval 5 \
       --max-summaries 2 \
       --no-super-rerank \
       --disable-ii
   ```

4. **If you need the full power** – keep the heavy settings but **pre‑warm** the vector store and embeddings (run a few cheap queries first) so that the index is loaded in memory.

5. **Consider network latency** – If you’re hitting a remote LLM API (OpenAI, Anthropic, etc.), the round‑trip can dominate. Test the same query locally with a tiny open‑source model (`--model llama-2-7b`) to see the baseline.

---

## Quick “why is it slow?” answer in plain English

`rag query` does more than a simple keyword lookup:

1. **It searches your knowledge‑base** (vector/TF‑IDF retrieval) – the larger the result set (`max_retrieval`) the longer it takes.  
2. **It may re‑rank those results** (`super_rerank`), which is an expensive cross‑encoder computation.  
3. **It builds a prompt** that contains the retrieved chunks and sends it to an LLM. The LLM’s inference time grows with model size, token count, and remote‑API latency.  
4. **If you ask for the `--agent` mode**, the tool spawns an autonomous agent that can run many extra LLM calls and file‑system scans, making the whole process much slower.

Turning any of those steps off or limiting their scope (fewer chunks, no rerank, smaller model, normal mode) will dramatically reduce the wall‑clock time.

---

### Example of a fast, still useful query

```bash
rag query "How do I add a new document to my knowledge base?" \
    --max-retrieval 3 \
    --max-summaries 1 \
    --no-super-rerank \
    --disable-ii \
    --json
```

- Retrieves only the top 3 most relevant chunks.  
- Summarises a single chunk (keeps the prompt tiny).  
- Skips the expensive rerank and in‑context retrieval.  
- Returns JSON so you can pipe it elsewhere.

If you later discover you need more context, bump the numbers up a little—​you’ll see the latency increase accordingly, which helps you balance speed vs. answer quality.

---

**Bottom line:**  
`rag query` is sometimes “terribly slow” because it is doing *retrieval‑augmented generation* (search, optional rerank, LLM inference). Use the logging tools (`dump_log`, `dump_api_usage`) to pinpoint which stage is the bottleneck, then tune the corresponding options (`--max-retrieval`, `--max-summaries`, `--no-super-rerank`, avoid `--agent`, pick a faster model). This will give you the speed you need while still leveraging the knowledge‑base when you really want it.

The `rag query` command can be slow because it uses a large language model (LLM) to answer questions, and this process can be computationally expensive. Additionally, the command may need to access a knowledge base that has been built using the `rag build` command, which can also be a time-consuming process.

Some possible reasons for the slowness include:

1. **Model complexity**: The LLM used by `rag query` can be complex and require significant computational resources, leading to slower response times.
2. **Knowledge base size**: If the knowledge base is large, it may take longer for the `rag query` command to search and retrieve relevant information.
3. **Network latency**: If the LLM is hosted on a remote server, network latency can contribute to slower response times.
4. **Configuration settings**: The configuration settings used by `rag query`, such as the model, chunk size, and timeout, can affect performance.

To improve performance, you can try optimizing the configuration settings, using a faster model, or reducing the size of the knowledge base. You can also use the `rag config` command to adjust settings such as the model, timeout, and chunk size to find a balance between accuracy and speed.

Based on the documents you provided, here are a few reasons why the `rag query` command might be slow:

*   **RAG Pipeline Steps:** The `rag query` command involves multiple steps, including extracting search keywords using an LLM, running a TF-IDF search, re-ranking chunks, and then generating a response. Each of these steps can contribute to the overall time.
*   **LLM Performance:** The speed of the LLM used for keyword extraction (step 2) and re-ranking (step 4) can significantly impact the query time.
*   **TF-IDF Search:** While TF-IDF search is generally fast, it can still take time depending on the size of your knowledge base.
*   **Model Choice:** The default model (`llama3.3-70b-groq`) might be slower than other models. You can try using a faster model like `gpt-4o-mini` by running `rag config --set model gpt-4o-mini`.
*   **API Latency:** If you're using a proprietary API (like Groq or OpenAI), network latency and API processing time can add to the delay.
*   **Number of Chunks:** The configuration settings for `max_summaries` (number of chunks retrieved from TF-IDF) and `max_retrieval` (number of chunks selected after re-ranking) can impact the time it takes to process the query. Retrieving and processing more chunks will generally take longer.

-- query (44.46s) --
Of course! Based on the documents you've provided, here are the main reasons why the `rag query` command can sometimes be slow.

The primary reason is that a single `rag query` command actually involves **multiple calls to an LLM** as part of its pipeline. Each call adds time due to network latency and the processing time required by the LLM service.

Here's the step-by-step breakdown of a normal query, as described in the documents:

1.  **Keyword Extraction (1st LLM Call):** First, an LLM analyzes your natural language query (e.g., "How does this server implement user authentication?") and extracts a list of relevant search keywords (e.g., "server, authentication, login, 2fa, jwt").

2.  **TF-IDF Search (Local):** The tool then uses these keywords to perform a fast, local search (TF-IDF) to find an initial set of potentially relevant document chunks (e.g., the top 10).

3.  **Reranking (2nd LLM Call):** Because the initial search isn't perfect, an LLM is used again to review the titles and summaries of those 10 chunks. It then "reranks" them to select the 3 most relevant ones for answering your question.

4.  **Final Answer Generation (3rd LLM Call):** Finally, the selected chunks are sent to the LLM along with your original query to generate the final answer.

As you can see, a standard query makes **three separate calls to an LLM**. The slowness you experience can be influenced by:

*   **Network conditions** between your machine and the LLM provider.
*   **The current load** on the LLM provider's servers.
*   **The specific mode** you are using. The documentation explicitly states that **`--agent` mode** is the "strongest and the most expensive way to get an answer" and can be "overkill for a simple question," which suggests it is likely much slower than a normal query.

### How to Investigate

If you want to see what's happening behind the scenes, the documentation suggests you can **enable logging**:

*   Run `rag config --set dump_log true`.
*   This will save log files in the `.ragit/logs` directory for any command that uses an LLM, allowing you to see the different steps as they happen.

This knowledge base contains the source code and documentation for a program called RAGIT.

RAGIT is a git-like command-line tool written in Rust for creating and sharing knowledge bases from local files. It uniquely uses AI-generated keywords and TF-IDF for search, rather than traditional vector search. It also enriches data with titles and summaries to improve AI-driven reranking and supports markdown files, images, and multi-turn queries.

The files are structured as follows: `README.md` for the main overview, `docs/` for detailed documentation on commands and concepts, `crates/` for the Rust source code organized into modules like `api` and `fs`, `tests/` for test files, and `RelNotes/` for release notes.

The `rag query` command can be slow due to several factors related to how it processes information, particularly when using advanced modes or relying on Large Language Models (LLMs) for various steps.

Here's a breakdown of the reasons based on the provided documents:

1.  **LLM Involvements in the RAG Pipeline:**
    *   **Keyword Extraction (Step 2):** Before even searching, an LLM is used to extract relevant search keywords from your initial query (e.g., transforming "How does this server implement user authentication?" into "server, authentication, login, 2fa, jwt"). This interaction with an LLM adds to the processing time.
    *   **Chunk Reranking (Step 4):** After an initial TF-IDF search retrieves a number of chunks (e.g., 10), an LLM is used *again* to review the titles and summaries of these chunks and select the most relevant ones (e.g., 3). This step is crucial for accuracy but contributes to the overall slowness.
    *   **Final RAG (Step 5):** The ultimate answer generation is done by an LLM, integrating the retrieved chunks. This is the core LLM interaction where the final response is produced.

2.  **Number of Chunks Processed:**
    *   The `max_summaries` configuration dictates how many chunks are retrieved by the TF-IDF search (defaulting to 10 but configurable). More chunks mean more data for the LLM to review during the reranking step, which can increase processing time.
    *   The `max_retrieval` configuration determines how many chunks the LLM ultimately selects for the final RAG (defaulting to 3 but configurable). While fewer final chunks might seem faster, the preceding reranking step still needs to process the larger set.

3.  **Mode of Operation:**
    *   **Normal Mode:** This runs a standard pipeline, which still involves multiple LLM calls as described above.
    *   **`--interactive` mode:** While it allows for conversations, the underlying RAG pipeline still executes for each turn, potentially leading to perceived slowness if each turn involves significant processing.
    *   **`--agent` mode:** This is explicitly stated as "the strongest and the most expensive way to get an answer." An agent browses files, which is a more complex process and will naturally take longer and incur higher costs. The documentation even suggests running `rag gc --audit` before and `rag audit` after to see the cost, indicating its resource intensiveness.

4.  **LLM Performance Itself:** The speed of the LLM model used can also be a factor. The `--model` option allows you to specify an LLM, and different models have different latencies.

In summary, the slowness of `rag query` often stems from its reliance on multiple LLM calls throughout its RAG pipeline for keyword extraction, reranking, and final answer generation, especially when combined with the complexity of modes like `--agent` or when processing a larger number of retrieved chunks.

Based on the documents you provided, the `rag query` command can be slow because it involves multiple LLM calls in its pipeline:

**The `rag query` command follows a 5-step process:**

1. **Step 2 - Keyword Extraction**: LLM extracts search keywords from your query
2. **Step 3 - TF-IDF Search**: Retrieves top chunks (default 10, configurable with `max_summaries`)  
3. **Step 4 - Reranking**: LLM reviews and reranks chunks to select the most relevant ones (default 3, configurable with `max_retrieval`)
4. **Step 5 - RAG Generation**: LLM generates the final answer based on selected chunks

**Why it's slow:**
- **Multiple LLM calls**: The pipeline requires at least 3 separate LLM API calls (steps 2, 4, and 5)
- **API latency**: Each LLM call has network latency and processing time
- **Large chunk processing**: In step 4, the LLM has to review titles and summaries of all retrieved chunks

**To investigate performance:**
- Enable logging with `rag config --set dump_log true` to see detailed logs in `.ragit/logs`
- Enable API usage tracking with `rag config --set dump_api_usage true` and use `rag audit` to see token usage

**Potential optimizations:**
- Reduce `max_summaries` (fewer chunks to retrieve and rerank)
- Reduce `max_retrieval` (fewer chunks for final RAG)

The multiple LLM API calls are the main bottleneck, especially if you're using a slower LLM provider or have high network latency.

Based on the documentation provided, `rag query` can be slow due to the multi-step RAG pipeline it uses:

1. **LLM keyword extraction (Step 2)** - The LLM extracts search keywords from your query
2. **TF-IDF search (Step 3)** - It retrieves the top chunks (default 10, configurable via `max_summaries`)
3. **LLM reranking (Step 4)** - The LLM reviews titles and summaries of all retrieved chunks to select the most relevant ones (default 3, configurable via `max_retrieval`)
4. **LLM RAG response generation (Step 5)** - Finally, it generates the answer based on the selected chunks

Each of these steps involving LLM calls can add latency. Additionally, if you're using `--agent` mode, the documentation explicitly notes it's "the strongest and the most expensive way to get an answer," which would be even slower.

**To speed things up, you could try:**
- Reducing `max_summaries` (currently defaults to 10) to retrieve fewer initial chunks
- Reducing `max_retrieval` (currently defaults to 3) to rerank fewer chunks
- Avoiding `--agent` mode for simple questions
- Using a faster LLM model via the `--model` option

You can check your actual performance with `rag audit` to see which steps are taking the most time.

Based on the documents provided, the `rag query` command can be slow because it goes through a **multi-step RAG pipeline** that involves multiple LLM calls:

## Why it's slow:

1. **Step 2 - Keyword Extraction**: The command first calls an LLM to extract search keywords from your natural language query (e.g., transforming "How does this server implement user authentication?" into keywords like "server, authentication, 2fa, login, jwt")

2. **Step 3 - TF-IDF Search**: It runs a TF-IDF search to retrieve the top N chunks (default 10, configurable via `max_summaries`)

3. **Step 4 - Reranking**: Another LLM call reviews the titles and summaries of all retrieved chunks to select the most relevant ones (default 3, configurable via `max_retrieval`)

4. **Step 5 - RAG Generation**: Finally, a third LLM call generates the actual answer based on the selected chunks

## What makes it slower:

- **Multiple LLM API calls** (at least 3 per query)
- **Higher retrieval settings** - if you've configured `max_summaries` or `max_retrieval` to higher values, it processes more chunks
- **Network latency** when calling LLM APIs

The slowness is inherent to the design, as it prioritizes accuracy through multiple refinement steps rather than speed.

Based on the documents provided, I can explain why the `rag query` command can be slow.

The `rag query` command involves **multiple LLM calls** in its pipeline:

1. **Step 2**: LLM extracts search-keywords from your query
2. **Step 4**: LLM reranks and selects the most relevant chunks from the tfidf results
3. **Step 5**: LLM generates the final answer based on the retrieved chunks

That's **at least 3 separate LLM calls** for a single query, which can add up in terms of latency, especially if you're using a remote API.

## Tips to investigate and potentially speed things up:

1. **Enable logs** to see where time is being spent:
   ```
   rag config --set dump_log true
   ```
   Logs will be saved in `.ragit/logs`

2. **Reduce the number of chunks** being processed:
   - `rag config --set max_summaries <number>` - reduces chunks retrieved from tfidf (default: 10)
   - `rag config --set max_retrieval <number>` - reduces chunks selected for final RAG (default: 3)

   Fewer chunks means less work for the LLM in the reranking step.

3. **Enable API usage logging** to see token counts:
   ```
   rag config --set dump_api_usage true
   ```

The slowness is likely due to network latency to the LLM API and/or the amount of content being processed in each step.
