Start with src/benchmarks/micro/runtime/Benchstones/BenchI/8Queens.cs and reproduce Benchstone.BenchI.EightQueens with the provided benchmarks_ci.py command. Compare the baseline and regression commits, then use the linked test report and profiling workflow to identify the cause. Done means the regression is explained and corrected, with the benchmark no longer showing the reported slowdown.
