event-performance

Overview ¶

Command eventperf is the Phase -1 measurement harness for Wails v3 Go→JS event dispatch.

It exists to answer one question with numbers instead of argument: does high-frequency event dispatch leak memory in the WebKit content process, and if so is the growth driven by call COUNT or by payload BYTES?

It drives events straight at WebviewWindow.DispatchWailsEvent — the exact entry point that performs the evaluateJavaScript call — so the measurement is of the transport, not of the runtime's listener plumbing or the application-level fanout.

Build/run (macOS):

go run ./tests/event-performance -duration 30s
