Start with the benchmark source at src/benchmarks/micro/libraries/System.Collections/TryGetValue/TryGetValueTrue.cs#L127-L136 and read the benchmarking workflow linked in the issue. Run the provided benchmarks_ci.py command for the System.Collections.TryGetValueTrue filter, then compare the result with the linked baseline and test reports. Done means the regression is understood and the benchmark result is verified against the baseline.
