Start with the benchmark sources linked at src/benchmarks/micro/libraries/System.Numerics.Vectors/Perf_VectorOfT.cs and src/benchmarks/micro/libraries/System.Memory/MemoryMarshal.cs. Run the two listed benchmarks with benchmarks_ci.py, then compare their results with the baseline and comparison commits. The issue does not define a code change or acceptance criteria, so reproduction and a recorded triage outcome are the available definition of done.
