Start with the benchmark source at src/benchmarks/micro/libraries/System.Collections/TryGetValue/TryGetValueTrue.cs, especially the SortedList and SortedDictionary cases, and read the benchmarking workflow linked in the issue. Run the provided benchmarks_ci.py command to reproduce the reported results. Done means identifying and documenting the cause of the measured improvement or confirming that no runtime action is needed.
