Start with src/benchmarks/micro/libraries/Microsoft.Extensions.Logging/ScopesOverheadBenchmark.cs and compare the baseline and compare commits linked in the report. Run the documented benchmarks_ci.py command for ScopesOverheadBenchmark, then identify the change responsible for both reported regressions and confirm the benchmark results no longer regress.
