Start with the linked DecodeTga.cs benchmark source and run the provided benchmarks_ci.py command for SixLabors.ImageSharp.Benchmarks.Codecs.DecodeTga*. Compare the baseline and test commits, then use the benchmark report and linked history to identify the regression. Done means the performance change is explained and the benchmark no longer shows the reported regression.
