Seems to be caused by: #104904. @carlossanlop. We are only seeing this regression on Linux.

[carlossanlop]

I don't know what changed. I also saw the results for arm64 Linux, they're really bad and conflict with what we got in this previous report with a ton of improvements: dotnet/perf-autofiling-issues#38280
