Start with the linked benchmark source at src/benchmarks/micro/libraries/System.Collections/TryGetValue/TryGetValueTrue.cs#L94-L103 and the benchmarking workflow documentation. Run the provided benchmarks_ci.py command, then review the linked test report and comparison data for the ARM64 AzureLinux result. Done would mean determining whether the reported improvement requires a runtime change and recording the triage outcome.
