Filter to possible package paths before trying to resolve a module. by falsedrow · Pull Request #18038 · python/mypy (original) (raw)

Okay, I benchmarked ac79825 as the following on mypy -c 'import torch' (see #17948 for description of the environments):

• 1.09x faster in long environment
• 1.06x faster in openai environment
• 1.42x faster in long environment (incremental)
• 1.22x faster in openai environment (incremental)

I'll check the extra normpath is slowing us down, if so should be very easy to save (update: looks like this might be a few 100ms, so a couple more percent)

Doing this also uncovered a minor regression from #15347 , which I shall try to fix... (update: I think best done in a new PR)
