That's a pretty big claim. I don't doubt that a lot of uv's benefits are algo. But everything? Considering that running non IO-bound native code should be an order of magnitude faster than python.

Its a pretty well-supported claim. uv skips doing a number of things that generate file I/O. File I/O is far more costly than the difference in raw computation. pip can't drop those for compatibility reasons.
