14:29 <cfbolz> performance is hard :-(

14:29 <cfbolz> https://github.com/python/cpython/issues/109049

14:30 <cfbolz> "We did see performance gains for several Python releases, but 3.12 seems to go back to the performance of 3.9 (at least CI wise)."

15:14 <antocuni> quoting some random comment in the issue:

15:14 <antocuni> > Like I said, if you believe this is a dictionary performance regression, you should be able to isolate the dict operation, do it in a loop and stop-watch it - it should show the regression. Otherwise, I don't think this worth investigation from CPython's perspective.

15:14 <antocuni> I think that this will be less and less true considering the changes in the CPython VM

15:14 <antocuni> the era of pretty-deterministic-performance is gone

15:15 <Dejan> depends on weather conditions

15:15 <Dejan> :D

22:51 <Hodgestar> The 3.12 performance regression shows up in my current work code base too.
