Start with the TryGetValueTrue benchmark source in src/benchmarks/micro/libraries/System.Collections/TryGetValue/TryGetValueTrue.cs and the linked test report. Follow the benchmarking workflow documentation and run the provided benchmarks_ci.py command to confirm the result against the listed baseline and test commits. Done means the improvement is reproducible and its runtime cause or follow-up is documented.
