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

Start with the linked benchmark source, src/benchmarks/micro/libraries/System.Threading/Perf.CancellationToken.cs, and run the provided benchmarks_ci.py command for System.Threading.Tests.Perf_CancellationToken. Review the linked test report and comparison data for CreateManyRegisterMultipleDispose. The issue does not define a code change or acceptance criteria, so completion requires triage to identify the intended performance work.
