Start with the benchmark source at src/benchmarks/micro/libraries/System.Collections/TryGetValue/TryGetValueTrue.cs, then review the linked test report and comparison data for the SortedDictionary and SortedList cases. Run the provided benchmarks_ci.py command to reproduce the measurements; done would require a clearly defined performance change and confirming its effect in the report.
