Start with src/benchmarks/micro/libraries/System.Reflection.Metadata/Perf.TypeName.cs at the linked Parse_AssemblyQualifiedName benchmarks, then run scripts/benchmarks_ci.py with the listed filter. Compare the reported baseline and test results to determine whether the improvement is reproducible; done means the benchmark result and any follow-up are validated.
