Installing binary packages using the #portage package manager feels like watching paint dry, compared to other package managers. I can count multiple seconds per package, even when said package is empty (e.g. a virtual).
I've always wondered why that is. It *feels* wrong, and nobody has managed to explain it to me.
A few days ago, while waiting multiple hours for 1500 packages to install into a clean root, it finally bothered me enough to dig into it.
