Start with src/benchmarks/micro/libraries/System.Numerics.Tensors/Perf_NumberTensorPrimitives.cs and the reported System.Numerics.Tensors.Tests.Perf_NumberTensorPrimitives benchmarks. Run the provided benchmarks_ci.py filters using the benchmarking workflow documentation, then compare the reported results. The issue does not define a code change or completion criterion, so further triage is needed before implementation.
