[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.Collections/TryGetValue/TryGetValueTrue.cs#L127-L136 and run the provided benchmarks_ci.py command. Inspect the linked benchmark and test reports for the ImmutableSortedDictionary result, then compare the listed baseline and test commits. Done means the performance change has a confirmed explanation and a recorded next action.
