Start with the benchmark source at src/benchmarks/micro/runtime/Exceptions/Handling.cs lines 380-395 and 418-433, then run the provided benchmarks_ci.py command using the Exceptions.Handling filter. Compare the reported baseline and test results across the linked commits and determine the cause of both regressions; done means the regressions are explained and addressed or otherwise documented.
