Indeed, but unzipping while downloading do. Analysing multiple metadata files and exporting lock data as well.

Now I believe unzip releases the GIL already so we could already benefit from that and the rest likely don't dominate perfs.

But still, rust software is faster on average than python software.

After all, all those things are possible in python, and yet we haven't seen them all in one package manager before uv.

Maybe the strongest advantage of rust, on top of very clean and fast default behaviors, is that it attracts people that care about speed, safety and correctness. And those devs are more likely to spend time implementing fast software.

Thought the main benefit of uv is not that it's fast. It's very nice, and opens more use cases, but it's not the killer feature.

The killer feature is, being a stand alone executable, it bypasses all python bootstrapping problems.

Again, that could technically be achieved in python, but friction is a strong force.
