I finally found an odd fix, not sure why it worked this way, but I thought to
pass it along on the hope that maybe it will work for you as well as it did for
me.  My max upload is  about 38KBPS, my max download is about 160KBPS.  I'd set
for to -1, so that the u/d rates would be set to infinite, so that the torrent
client would intelligently choose the best rate.  But my experience showed that
my max ACTUAL gross download was only about 25KBPS (remember, I was expecting,
from the torrent protocol, to get better than 6 times that.)

Well, finally losing all hope, I decided to set the upload rate down to about
20K, so I could use the reserved rate for other entertainments.  IMMEDIATELY
upon limiting the UPLOAD rate to 20K, the download rate shot up to nearly my
160K maximum.  I can't understand this, but I tried to move the upload/download
rates around a little bit, to verify the finding: that I just should NEVER set
the rates to infinite, and that (at least in ktorrent) the max download rate
really was attainable.

I haven't any idea why this worked for me, only that it did do this, reliably.
I may go back to trying previous torrent clients now.  What a fine way to spend
the afternoon!
