stream-performance

Overview ¶

Command streamperf is the load harness for GoStream.

It answers the questions the design could not answer by argument: how much throughput a held-poll transport sustains Go→JS, whether anything is lost or reordered under load, what it costs in host and content-process memory, and how long a Send blocks.

It drives StreamConn.Send directly — the transport entry point — so what is measured is the transport, not application-level fanout.

Run (macOS):

go run ./tests/stream-performance -duration 20s

One scenario only:

go run ./tests/stream-performance -only rate-5000
