How to Benchmark WebSocket RPC: First Message, Gaps and Reconnects
Benchmarking WebSocket providers requires subscription quality and recovery metrics, not only handshake latency.
Benchmarking WebSocket providers requires subscription quality and recovery metrics, not only handshake latency.
Connection phases
Measure DNS, TLS, upgrade, subscription acknowledgement and time to first real event.
Stream quality
Track event age, sequence or slot gaps, duplicate messages and silent periods while the socket remains open.
Recovery
Force disconnects and measure reconnect, re-subscription and state-reconciliation time with jittered backoff.
Fair comparison
Use the same subscription, region and observation window. Compare provider events against an independent reference stream.
