I'm not able to reproduce on M1. Maybe a Windows-only issue? Could you update the description? It looks like the numbers are inverted. It would be helpful if you could trim the reproduction to the minimal form where you see the perf difference so it is easier for others to debug.

I was able to reproduce on Windows. It seems it's happening from 3.2.0-beta.0.
