[Profiling workflow for dotnet/runtime repository](https://github.com/dotnet/performance/blob/master/docs/profiling-workflow-dotnet-runtime.md)
[Benchmarking workflow for dotnet/runtime repository](https://github.com/dotnet/performance/blob/master/docs/benchmarking-workflow-dotnet-runtime.md)

Start with the benchmark source in performance/src/benchmarks/micro/libraries/System.Numerics.Tensors/Perf_FloatingPointTensorPrimitives.cs, then review the linked benchmark and profiling workflow documents. Rerun the supplied benchmarks_ci.py command for the Sigmoid case and compare the reported baseline and test results. Done means identifying whether the improvement is reproducible and what follow-up, if any, is warranted.
