Hyperliquid REST vs WebSocket Benchmark: What to Measure

A benchmark plan for Hyperliquid market data that separates request latency from streaming freshness and recovery.

REST tests

Measure representative info requests with connection reuse, payload validation and rate-limit behavior.

WebSocket tests

Measure connection setup, subscription acknowledgement, time to first update, event age and gap frequency.

Clock discipline

Synchronize the benchmark host and preserve local receive time. Without clock quality, freshness claims are unreliable.

Trading relevance

Relate data latency to quote age, cancellation time and realized mark-outs rather than treating milliseconds as the final outcome.
