How to Benchmark WebSocket RPC: First Message, Gaps and Reconnects

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.
