How fast is Python 3.15?

It's October once again, and that means it is time to take the new release of Python for a spin. As I did with my Python 3.14 performance article of a year ago, today I'm sharing a new run of my informal Python benchmark, comparing Python 3.15 against previous interpreters all the way back to 3.10. If you are not interested in the charts and the tables and just want to read my analysis, feel free to jump to the conclusions section at the end.
