## What is PSRT

PSRT is a pub/sub real-time telemetry protocol, optimized for industrial needs:
providing low latency, dealing with slow channels and large payloads.

PSRT can process 100K+ messages on a single node with very low latencies
(<1ms). Speeds are reasonable (1K+ ops/sec) even with enormous (1MB+) payloads.

Topic subscriptions in PSRT are processed with B-tree algorithms, which allows
the server to handle hundred thousands subscriptions without any speed
loss.
