> The only advantage of uv is to have support for parallel async extraction. If pip extracted multiple files/wheels in parallel without being blocked by the GIL, pip could easily match or outcompete uv.

That sounds like it would be relatively easy to demonstrate: You could tweak uv to perform downloads/extractions sequentially and then compare its runtime with pip. Has any such comparison been done?

I haven't done the comparison but it shouldn't be so hard

		Fun fact! The original request to add a concurrency variable in uv was requested by me because, among other things, I wanted to measure the difference between uv and pip: https://github.com/astral-sh/uv/issues/3311 I'm not really following this performance discussion as I think it's gone off the rails.
