[Profiling workflow for dotnet/runtime repository](https://github.com/dotnet/performance/blob/master/docs/profiling-workflow-dotnet-runtime.md)
[Benchmarking workflow for dotnet/runtime repository](https://github.com/dotnet/performance/blob/master/docs/benchmarking-workflow-dotnet-runtime.md)

Start with the System.Threading.Tasks.Tests.Perf_AsyncMethods.Yield benchmark source at src/benchmarks/micro/libraries/System.Threading.Tasks/Perf.AsyncMethods.cs and run the provided benchmarks_ci.py command. Compare the listed baseline and test commits, then use the profiling workflow to investigate the regression. Done means identifying the cause and validating the result against the reported performance difference.
