Start with the two linked benchmark source files, Perf_VectorOfT.cs and MemoryMarshal.cs, and reproduce both filters with the provided benchmarks_ci.py commands. Compare the reported baseline and test timings, then inspect the linked test reports and profiling workflow docs. Done means the improvement is explained or validated and any necessary follow-up is identified.
