Package: apt
Version: 0.7.14

apt-get apparently currently uses some simple wget-type sequential
download algorithm for all its functions that download anything from
the net, like update, install, dist-upgrade, upgrade, build-dep,
source etc. This really does not well use the available broadband
bandwidth of most users. Hence I am forced to use home-cooked scripts
to extract the URLs to download and then pass them to aria2 (GPL) to
download, so that the thing is done faster. If it is built-in,
everyone can benefit.

Granted, the user may not want his entire bandwidth hogged by apt-get,
but at least provide this as an option -- use a faster split-download
algorithm, or at least use a good backend downloader like aria2 which
provides high-speed downloading.

I am a downstream (Ubuntu) user of Debian apt, and the downstream
people redirected me to here from

This was never implemented as it is indeed not nice for mirrors.  The
advent of various scripts doing it anyway just shows how this would have
been and still would be missused to put pressure on the mirrors for no
gain and even worse results in the long run.

What should be done can serve as a good and nice quasi-replacement are
redirector services like httpredir.debian.org which will use up all your
bandwidth while being nice to mirrors (and in fact distributing the load
better as even new and unknown mirrors will be used automatically).

Hence closing as "superseded by a better idea with working
implementation".
