Start with src/benchmarks/micro/libraries/System.Numerics.Vectors/Perf_Matrix3x2.cs and the linked benchmark report for AddBenchmark and AddOperatorBenchmark. Run the provided benchmarks_ci.py command using the System.Numerics.Tests.Perf_Matrix3x2 filter, then investigate the reported WebAssembly measurements; the payload does not define a specific code change or completion criterion.
