Germán Méndez Bravo 03648a2a91 bpo-43392: Optimize repeated calls to __import__() (GH-24735) ... Implements a two steps check in `importlib._bootstrap._find_and_load()` to avoid locking when the module has been already imported and it's ready. --- Using `importlib.__import__()`, after this, does show a big difference: Before: ``` $ ./python -c 'import timeit; print(timeit.timeit("__import__(\"timeit\")", setup="from importlib import __import__"))' 15.92248619502061 ``` After: ``` $ ./python -c 'import timeit; print(timeit.timeit("__import__(\"timeit\")", setup="from importlib import __import__"))' 1.206068897008663 ``` ---		2021-08-12 11:23:29 -07:00
