That's a horse of a different color.  The OP said something about having 
dedicated servers with a 100mbit link to the net.  If you're hanging off 
a cablemodem you're pretty much at the mercy of your cable provider.  I 
know folks who have gotten their ports throttled and/or turned off for 
no apparent reason only to get an "oops" or "you must have been doing 
something wrong" type of response when they called to report trouble 
with their connection.

I generally leave a copy of the latest DVD torrent available on one of 
my older servers at the datacenter, but I limit upstream throughput to 
about 30kbit/sec.   I just experimented with setting it to "unlimited" 
and my upstream traffic immediately spiked up to about 6mbits/sec....so 
I put it back to the way it was.  :)
