Having a local "bare" copy (to use Git's term; `hg clone -U`) of the Mozilla repo, I'd like to create a checkout of it (`hg clone`), and build Firefox from it.
This results in 90 minutes of waiting with hg pegging one CPU core (CPU-bound, not disk-bound!), then a few minutes of hg actually writing files, then the actual build taking 60 minutes.
In the git community, it was always taken as a sign that they were doing something right that `git clone` was faster than `cp -r`. I'm having a hard time not taking it as a sign that Mercurial is doing something wrong that `hg clone` is so much slower.
edit: The saying was that `git checkout` is faster than `cp -r`, not that `git clone` is. The sentiment stands.
