What rates do other folks see?
I've seen over 400 kBps (kilobytes per second) incoming on BitTorrent with
my Comcast feed. This is going through a LinkSys WRT54G router with ports
forwarded. I've limited my BT upload rate to 26 kBps; I seem to do best with
that number. YMMV.
Fastest I've ever seen on this feed, period, is just over 500 kBps from an
idle FTP server with a fast pipe. Mmmmmm. :)
FYI:
BitTorrent works by having a central "tracker" manage the torrent
distribution. As each client successfully downloads a piece of the torrent,
it becomes a potential server for same. The more pieces your own client
serves up, the more peers the tracker gives you to download from. The BT docs
call this "tit-for-tat". It keeps leaches from killing the system.
If you don't have much of the torrent downloaded yet, your download rate
will be low. It will climb as you download more pieces and can thus upload
more pieces. Give it time.
If peers are having trouble connecting to you for their downloads (say,
because of a firewall or NAT), your download rate will be low.
If your pipe is asymmetric (i.e., most cable and DSL feeds), your download
rate will be lower then it could be with a symmetric pipe, but still do pretty
well.
If you saturate your outgoing channel, you can actually reduce your incoming
rate. So it's best to limit your upload rate to something like 90% of your
theoretical maximum. *handwave*
Finally, an overloaded tracker will kill everyone's download rates, and a
poorly seeded torrent (few peers with the entire torrent available) will do
likewise, so sometimes it is out of your control.
Disclaimer: I'm no expert on BitTorrent, but I've read a FAQ or two, and can
parrot them well. :-)
