Only PR in the compare list: https://github.com/dotnet/runtime/pull/106578 @jkotas. It is not clear how this PR would cause all of this impact though (Regressions and Improvements). Only the Regressions in System.Text.Tests.Perf_StringBuilder seem likely to be not noise, keeping the rest just incase though.

We have picked up build images with new version of the C/C++ compilers at the same time. The build image updates are not submitted as PRs. They just happen in the background.
This PR fixed build break introduced by the new version of the compilers, so the regression got attributed to it. I believe that the C/C++ compiler update is responsible for the regressions and improvements. I expect that some of these will go away once we pick up fresh C/C++ PGO data collected on binaries produced by the new compilers.
