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

Start with the benchmark source at performance/src/benchmarks/micro/libraries/System.IO.Pipelines/Perf.Pipe.cs#L99-L115 and the linked ReadAsyncWithCancellationToken report. Run the provided benchmarks_ci.py command to reproduce the Windows improvement and compare the baseline and test results. The issue does not define a code change or acceptance condition, so completion would require triage to identify and validate an actionable runtime improvement.
