[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.Linq/Perf.ImmutableArrayExtensions.cs#L29-L32 and the linked performance report. Run the provided benchmarks_ci.py command using the System.Linq.Tests.Perf_ImmutableArrayExtensions filter, then compare the reported baseline and test results. Done means the improvement is reproduced and its triage outcome is documented.
