Start with the DecodeTga benchmark source at src/benchmarks/real-world/ImageSharp/Codecs/DecodeTga.cs and the linked baseline/compare commits. Run the documented benchmarks_ci.py command to reproduce the Linux x64 result, then use the linked test report and comparison data to identify the source of the duration regression. Done means the regression is understood and a verified correction or triage outcome is recorded.
