Some suggestions for faster downloads without bittorrent.
1) use aria2c (or a similar application), which uses multiple 
connections, defaulting to 5, and allows multiple mirrors.
By default it starts by allocating space for the file to be downloaded, 
which allows non-sequential downloading of the file, facilitating faster 
downloading from multiple sites.

2) use mirrors which allow multiple connexions.
(Of course, with download software that takes advantage of this.)

3) use multiple mirrors.
(Again, according to download software.)

4) use ftp instead of http

5) use closer mirrors.  (less delay in handshaking, etc.)

In my case, using aria2c with 2 mirrors and the default 5 connexions is 
at least 3 times as fast as a single connexion (to my closest mirror).
And a much greater improvement over other download options I've tried.

I also have configured rpmdrake to use aria2c -- it seems to give me 
faster and more reliable updating, but I don't have any figures.

aria2c is a console app, but it works well enough for me that I haven't 
(yet) bothered to install the available GUI frontend.
