Start with the referenced LoggingOverheadBenchmark.cs sections at lines 25-29 and 38-42, then compare the supplied baseline and test commits. Run the documented benchmarks_ci.py command for the Microsoft.Extensions.Logging.LoggingOverhead filter and inspect the linked test report. Done means explaining and addressing both reported regressions, with follow-up measurements confirming the benchmark results.
