Start with the reported SixLabors.ImageSharp.Benchmarks.Codecs.Jpeg.DecodeJpeg benchmark source at src/benchmarks/real-world/ImageSharp/Codecs/Jpeg/DecodeJpeg.cs#L54-L55 and the linked baseline/compare commits. Run the provided benchmarks_ci.py command and review the benchmark report and profiling workflow to identify the regression; done means the cause is understood and the benchmark no longer shows the reported slowdown.
