### Docs

[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 benchmarking workflow documentation and reproduce the reported Startup - PaintDotNet - FDD Publish scenario using scripts/benchmarks_ci.py with the supplied filter. Compare the baseline and test reports, then use the profiling workflow and linked ETL, histogram, or JIT data to investigate. Done should mean the reported performance issue is understood and a measurable result is documented.
