### Docs

[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 linked benchmark source, performance report, and profiling and benchmarking workflow docs. Run benchmarks_ci.py with the supplied System.ConsoleTests.Perf_Console filter, then compare the ARM64 Azure Linux baseline and test results. Done means the reported ForegroundColor improvement is understood and any required follow-up is documented.
