Start with the baseline and compare commits, then follow the benchmarking workflow documentation and reproduce the SixLabors.ImageSharp.Benchmarks.Codecs.DecodeBmp filter using scripts/benchmarks_ci.py. Compare the reported 81.72 μs baseline with the 100.44 μs test result and use the linked benchmark and report pages to identify the regression. Done means the cause is identified and the benchmark no longer shows the reported regression.
