There is a report that python.org 3.11 Windows release has slowed down on micro benchmarks:
faster-cpython/ideas#420
One reason is that PyObject_Free() is not well optimized by the latest MSVC (ver.1932 in v143 tool set), which is likely to be used for the next 3.10 official as well.
This issue has been reported to the MSVC team. However, their tools would not be fixed urgently.
