Thanks for the investigation Dennis. Have you tried seeing if it improves anything with the coverage.py benchmarks ?

I haven't -- I was having trouble getting those to run on Windows.

I am on a PR to add a coverage benchmark to pyperformance to aid benchmarking. (python/pyperformance#213)

[kumaraditya303]

This results in a 20% speedup on main branch vs this branch:

Benchmark	3.12	PyCode_GetCode
coverage	204 ms	170 ms: 1.20x faster

Benchmark: python/pyperformance#213

This looks like a slight improvement. Not the 20% that @kumaraditya303 found, but worthwhile:

pyver	proj	6.4.1	#1394	#1394 vs 6.4.1
python3.11	bug1339.py	0.828 s	0.807 s	97%
python3.11	bm_sudoku.py	55.887 s	52.904 s	94%
python3.11	bm_spectral_norm.py	68.005 s	61.789 s	90%
