> 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.
What I understood is that the https://bugs.python.org/msg401743 patch makes 1.07x faster.
But https://bugs.python.org/issue45116#msg401143 compares Python 3.10b1 to Python 3.10a7: Python 3.10b1 is slower (32-bit: "1.07", 64-bit: "1.14": "higher the slower" wrote neonene).
