181 Benchmarking and Profiling Workflow

Optimization should be a controlled loop, not guesswork.

Workflow

baseline benchmark -> profile hotspot -> implement focused change -> remeasure -> keep/revert

Measurement Signals

  • ns/op for latency cost.
  • B/op and allocs/op for memory pressure.
  • CPU and heap profiles for hotspot attribution.

Process Discipline

Change one variable at a time and keep benchmark inputs stable. This is the only reliable way to attribute wins or regressions.
