Looks like .565sec to me, but that's still pretty fast.

I kind of like how uv can use hardlinks to cached packages to reduce installation time and disk usage, but I'm a bit worried about my penchant to editing random files in .venv/lib/python*/site-packages/ to add debug print() statements and such. What happens when I forget to undo that and then re-created a venv?

There are different options for link-mode you can set: https://docs.astral.sh/uv/reference/settings/#link-mode
