[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)

The benchmark source is performance/src/benchmarks/micro/runtime/perflab/LowLevelPerf.cs, around lines 283-290. Start by running the provided benchmarks_ci.py command with the PerfLabTests.LowLevelPerf filter and compare the Windows/x86 result with the linked baseline and compare commits. Use the linked benchmarking and profiling workflow docs; done means determining whether the StaticDelegate improvement needs follow-up or only triage.
