Benchmark Run Instructions

Running Benchmarks

  • Full suite: npm run benchmark
  • Single benchmark file:
    • Tree: npm run benchmark -- -t out-test/benchmark/Event.benchmark.js
    • Run file: npm run benchmark -- -s "out-test/benchmark/Event.benchmark.js" out-test/benchmark/Event.benchmark.js
  • Single context/case:
    • Use -t to get the path, then:
    • npm run benchmark -- -s "<path>" out-test/benchmark/Event.benchmark.js

Benchmark Case Selection

When writing benchmark instructions:

  • Use RuntimeCase to measure pure runtime in ms.
  • Use ThroughputRuntimeCase when measuring throughput in MB/s.

Notes

  • Benchmarks run from built JS in out-test/benchmark/*.benchmark.js.
  • Keep NODE_PATH=./out (handled by the npm script).
