Running a comparison with local changes

yarn benchmarks run-compare main
yarn benchmarks run-compare <compare-sha> [bazel-target]

If no benchmark target is specified, a prompt will allow you to select an available benchmark.

Running a comparison in a PR

You can start a comparison by adding a comment as follows to any PR:

/benchmark-compare main //modules/benchmarks/src/expanding_rows:perf_chromium

/benchmark-compare <other-sha> //modules/benchmarks/src/expanding_rows:perf_chromium

Note: An explicit benchmark target must be provided. You can use the prompt of yarn benchmarks run to discover available benchmarks.
