Research direction
Start with the benchmark definitions in performance/src/benchmarks/micro/libraries/System.Linq/Perf.Enumerable.cs at lines 319-321 and 325-327, then run the provided benchmarks_ci.py command for Perf_Enumerable. Compare the linked baseline and test reports for Min and Max; done means the reported regressions are explained and the benchmark results no longer show the regression.
