Research direction

Start with the linked benchmark source, src/benchmarks/micro/libraries/System.Runtime.Intrinsics/Perf_Vector128OfT.cs, and review the reported System.Runtime.Intrinsics.Tests.Perf_Vector128Of results and comparison links. Determine whether the improvement requires follow-up in the benchmark or runtime and document the triage outcome; the issue does not define a specific code change or test target.
