Start with the three named benchmark sources: IPAddressPerformanceTests.cs, XposMatrix.cs, and Linq.cs, then run the corresponding benchmarks using the provided benchmarks_ci.py commands. Compare the reported Windows/x86 results with the linked baseline and test commits; done means the performance findings have been investigated and an appropriate outcome is recorded.
