Start with the linked benchmark source at src/benchmarks/micro/libraries/System.Runtime/Perf.Boolean.cs and inspect the Parse and TryParse entries in the performance report. Run the provided benchmarks_ci.py command, then determine whether the reported ARM64 improvements need investigation; the issue does not define a requested change or completion criteria.
