[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.Runtime.Numerics/Perf.BigInteger.cs#L61-L64 and reproduce System.Numerics.Tests.Perf_BigInteger with the provided benchmarks_ci.py command. Compare the reported baseline and test results, then use the linked benchmark and profiling workflow documentation to investigate; done means establishing whether the improvement needs an actionable runtime change.
