Start with the referenced benchmark in src/benchmarks/micro/libraries/System.Diagnostics/Perf_Process.cs, especially GetCurrentProcessName, then review the linked test report and comparison commits. Determine whether the reported arm64 improvement is expected and identify the relevant runtime change; done means the result is explained or a specific follow-up is documented.
