Start with src/benchmarks/real-world/ImageSharp/Codecs/Jpeg/DecodeJpeg.cs, especially the JpegBaselineInterleaved444 benchmark, and run the provided benchmarks_ci.py command from the performance repository. Compare the result with the linked baseline and test commits and use the profiling workflow links for investigation. Done means the reported JPEG benchmark regression is resolved and the result is validated against the comparison.
