Thus the theory of torrent. Things that are popular will download
quickly, things that aren't won't. Seems to match well with community if
you ask me.
I just downloaded:
http://torrent.fedoraproject.org/torrents//F10-Snap1-x86_64-Live.torrent
It took just over 6 minutes and my top speed was 2037.3 KB/s I might
suggest that different places have different rules wrt torrent and qos,
firewalls and other setups can affect torrent preformance.
