Start with the benchmark source at src/benchmarks/micro/libraries/System.Numerics.Vectors/Perf_Quaternion.cs#L63-L64 and the benchmarking workflow linked in the issue. Run benchmarks_ci.py with the System.Numerics.Tests.Perf_Quaternion filter, then inspect the linked report and compared commits. Done means determining whether the reported CreateFromRotationMatrixBenchmark improvement is reproducible and what accounts for it.
