Start with the benchmark source at performance/src/benchmarks/micro/libraries/System.Numerics.Tensors/Perf_FloatingPointTensorPrimitives.cs, especially the Sinh case around lines 55-56. Run the supplied benchmarks_ci.py command and inspect the linked test report and comparison data for the x86 Windows configuration. Done means determining whether the reported Sinh improvement is actionable and validating the resulting performance behavior.
