## How to Update This Document

After running benchmarks:

1. **Run the full suite**:
   ```bash
   ./tests/benchmarks/run_benchmarks.sh
   ```

2. **Extract results** from:
   - `target/criterion/report/index.html` (interactive)
   - `tests/benchmarks/results/performance_report_*.md` (summary)
   - Console output during benchmark run

3. **Fill in the tables** above with actual measurements

4. **Add optimization recommendations** from the analysis report

5. **Track scaling factors** to identify O(n²) or worse complexity

6. **Save baseline**:
   ```bash
   cargo bench --bench marketplace_performance -- --save-baseline v1.0.0
   ```

## Performance Regression Detection

Before merging PRs, ensure:

- ✅ No operation regresses by > 10%
- ✅ No new Critical or High severity issues
- ✅ Memory usage stays within targets
- ✅ Scaling complexity remains acceptable

## Quick Status Check

```bash
# Run quick benchmarks (5-10 min)
./tests/benchmarks/quick_benchmark.sh

# Check if any operation is > 2x goal
grep "Critical" tests/benchmarks/results/performance_report_*.md

# View HTML report
open target/criterion/report/index.html
```
