Unless you have
file://mnt/mirror/debian unstable main
http://ftp.de.debian.org/debian unstable main
http://ftp.debian.org/debian unstable main
where you certainly want to get all files locally and only fall back
to the web on errors and there also first use the german mirror and
only fall back to ftp.d.o on error.
If parallelism like this gets added then there has to be a way to
enable/disbale it specifically. It is not generaly a good thing.
