+
+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.
