Start with the benchmark definitions in performance/src/benchmarks/micro/libraries/System.Numerics.Vectors/Perf_VectorOfT.cs at lines 116-117, 125-126, and 137-138, then compare the listed baseline and test commits. Run the provided benchmarks_ci.py command and inspect the linked test report and disassembly data. Done means the three reported regressions are understood and the benchmark results confirm the issue is resolved.
