@perfallit.bsky.socialNeed JSON before anything can read your benchmarks. The flags: `pytest-benchmark --benchmark-json=out.json`, `go test -bench . -benchmem -json`, `cargo criterion --message-format=json`, Google Benchmark's `--benchmark_format=json`. Pick one and the pipeline treats all four the same. #pytest…
@perfallit.bsky.socialRight, a benchmark check only verifies what you tell it to. Perfall's gate is exactly that and nothing more: you set the allowed percentage, and the CLI exits non-zero only when a change exceeds it. No claim it measures overall system performance. #benchmarking #CI #pytest #golang
@perfallit.bsky.socialCheat sheet of benchmark flags that emit machine readable JSON: pytest-benchmark writes JSON, go test takes -bench -benchmem -json, cargo criterion takes --message-format=json, Google Benchmark exports JSON. Parseable output is the part every regression gate builds on. #pytest-benchmark…
