Got myself a shiny python 3.13.3 (ssl module still unable to compile with libressl) replacing a 3.12.2, feels clearly slower.

What's wrong?

python 3.13 doesn't ship with free-threaded Python compiled AFAIK.

You mean it is not default anymore?

It's never been the default.

Did you compile the Python yourself? If so, you may need to add optimization flags https://devguide.python.org/getting-started/setup-building/i...

huh... then why it feels significantly slower since I did not touch the build conf.
