True, but poetry still has a long startup time (probably reading the lock file?) before it gets to the network parts. Also, a lot of the time spent in our projects is compiling/installing dependencies, not downloading them, and at least the install part could probably be sped up (I'm guessing async Rust is faster than whatever Poetry is doing).

But yeah, I'm not expecting huge wins here, but if it saves me a minute or so when rebuilding my docker images (currently takes >5 min in the poetry part alone), that's worth taking the time to switch.

I'm a lot more excited about projects like Ruff though, but any part of the Python tooling ecosystem is interesting.
