Start with the benchmarking workflow in docs/benchmarking-workflow-dotnet-runtime.md and reproduce each named benchmark using the provided benchmarks_ci.py commands. Compare the reported baseline and test timings, then inspect the linked performance reports and commit diff to identify the source of both regressions. Done means confirming the regression and addressing it or documenting the cause with benchmark results.
