Research direction

Start with src/benchmarks/real-world/ImageSharp/Codecs/Jpeg/DecodeJpeg.cs and EncodeTga.cs, then read the benchmarking workflow documentation. Rerun the two filters with benchmarks_ci.py and compare the reported results against the linked baseline and test reports. Done means producing a supported triage conclusion for both performance changes.
