[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 benchmark source at src/benchmarks/micro/libraries/System.Runtime.Extensions/Perf.Random.cs lines 17-18, then run the documented benchmarks_ci.py command for System.Tests.Perf_Random. Compare ctor_seeded with the linked baseline and test report; done means the performance result is reproduced and its cause or next action is documented.
