Start with src/benchmarks/real-world/ImageSharp/Processing/Diffuse.cs and run the documented benchmarks_ci.py command for SixLabors.ImageSharp.Benchmarks. Compare the baseline and test commits and inspect the linked benchmark and report data to identify the regression. Done means the DoDiffuse duration no longer shows the reported regression and the benchmark confirms the result.
