Good question, to which I do not know the answer! However, Python 3.11 included a lot of optimizations intended to make things faster. Speed has become a focus of Python and they are planning each odd-numbered revision to have speed improvements.

That said, on my machine I find this difference on each Python version!

Here are the results. Note the significant regression on Python 3.12; Python 3.13 is still beta and further improvements are expected.
