I use apt-get regularly, I also have some Debian systems, and the
progress meter doesn't reflect parallel downloads.
I have an Ubuntu system in the office and apt-get definitely does do
parallel downloads when updating its database ('update'), but I'm less
sure about downloading packages ('upgrade'). It's an Internet 2
connection which is very fast so maybe it can't be bothered :-). Adept
and synaptic are the same. I've also used apt-get on Fedora (a few years
back) and it definitely did parallel downloads of packages, probably
from different servers.
