If https://bugs.python.org/file50280/310rc2_benchmarks.txt is correct, this means that we have a 7% slowdown in Windows PGO builds for 3.10, which I don't think is acceptable.

I am marking this as a release blocker until there is some agreement. I remind you that if an agreement cannot be reached, you may reach the Steering Council for help reaching some conclusion.
