Obviously connectivity to git.gnome.org and svn.gnome.org may be quite
different - they are hosted in different places (svn.gnome.org in
Europe, git.gnome.org in the US)

But in every case we've looked at, bottlenecks checking out from
git.gnome.org:

 A) On someone's local connection or network provider
 B) Somewhere in hand-offs between major networks

With no network constraints, you should see download rates of
1 or 2 MiB/s. (I consistently get that from the Red Hat office in
Massachusetts, somewhat slower from home - but still 10x what you are
reporting.)

Of course, checking out everything is a one-time activity so almost by
definition it won't be the same in the future....
