I have a broadband 'Net connection, and apt could utilize this by pulling
multiple DEB files in parallel when those files are available from multiple
repository mirrors in sources.list.

I looked through the bug reports for apt and saw several bandwidth LIMITING
requests, this is the opposite.

When INDIVIDUAL DEB files are available, such as from volitile, Virtualbox,
debian-multimedia or backports, those DEB files are pulled by apt in
parallel while also pulling DEB files from the standard repositories.

So at the start of a serious update/upgrade/install, I see full network
utilization until the unique repositories are finished.

But when there is more than one repository in sources.list that contains
the same DEB files, only the first listed source is utilized so only a
single DEB file is being downloaded, one at a time, even if hundreds of
mirrored standard packages are being updated.

I have more than one "official" Debian mirrors in my sources.list, thank
you apt-spy, and if different DEB files were pulled from each of them in
parallel, this would better utilize my 'Net connection, as well as
spreading the load across different mirrors.

Thank you for listening,
