Start with src/benchmarks/micro/libraries/System.Collections/TryGetValue/TryGetValueTrue.cs at the linked benchmark lines, then run the documented benchmarks_ci.py command and compare the reported result with the baseline and test commits. Done means identifying and correcting the cause of the ConcurrentDictionary TryGetValue performance regression, then confirming the benchmark no longer shows the regression.
