Start by reading the linked benchmark source at src/benchmarks/real-world/ImageSharp/Codecs/Jpeg/DecodeJpeg.cs and the benchmarking workflow in docs/benchmarking-workflow-dotnet-runtime.md. Run the provided benchmarks_ci.py command, then compare the baseline and test commits and inspect the linked test report. Done means identifying the cause of the JpegProgressiveNonInterleaved420 regression and resolving or documenting it.
