Python 3.12 tests performance degradation

[hkad98]

Hello community,

I want to ask if someone encountered performance degradation for Python 3.12. Recently, I added support for It, and its performance is worse than that of 311, 310, 39, and 38.

Python version	Test execution time
3.12	4m 59s
3.11	2m 9s
3.10	2m 8s

Link to tests: /~https://github.com/gooddata/gooddata-python-sdk/actions/runs/9778991463/job/26997125183?pr=710

I use the latest version of pytest. I will keep investigating what is going on, and I will let you know if I find something.

this is a most curious an schocking data find

would i be possible/feasible to do profiler reports for those testruns to see whats causing that spike

I am seeing the same, happy to provide profiler reports later. The increase is exactly on the commit that switched to 3.12.
