Summary

  • Added a dedicated CodSpeed CI workflow (.github/workflows/codspeed.yml) that runs the ruff instrumented benchmarks (linter, lexer, parser, formatter) on every push to main and on pull requests.
  • Updated codspeed-criterion-compat and codspeed-divan-compat from v4.0.4 to v4.4.1.
  • Added the CodSpeed badge to the README.

The workflow uses the CodSpeed GitHub Action (v4.11.1) with OIDC authentication and runs benchmarks in simulation mode via cargo-codspeed.

Next steps

  • Once the initial run completes on main, CodSpeed will start tracking performance baselines.
  • Pull requests will automatically get performance regression checks.
  • Visit CodSpeed dashboard to view benchmark results and flame graphs.
