Start with src/benchmarks/micro/libraries/System.Runtime.Intrinsics/Perf_Vector128OfT.cs at lines 151-152 and the reported MultiplyBenchmark results. Run the provided benchmarks_ci.py filter, then compare the baseline and test reports for the WASM configuration. Done is identifying whether the reported improvement has an actionable cause; the issue does not specify a code change.
