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.
