Start with the GreaterThanAllBenchmark definition in src/benchmarks/micro/libraries/System.Numerics.Vectors/Perf_VectorOfT.cs at lines 116-117, then inspect the baseline-to-compare commit diff and the linked performance report. Reproduce the benchmark with the provided benchmarks_ci.py command and consult the profiling and benchmarking workflow documents. Done means identifying and addressing the source of the WebAssembly regression, with the benchmark no longer showing the reported slowdown.
