Dont forget fella that your download speeds with torrents (as indeed with all p2p applications) are limited by other users Upload
speeds, and the amount of seeds/downloaders on that torrent.
This is one of the reasons I rarely use it nowadays, if you know the sites to go onto, you can get a lot of stuff on Rapidshare, which will let you have it at 10Mbps or more.
Personally, the only the thing I use torrents for nowadays (other then the odd bit of well seeded software or music) is UK Nova for all the TV programs, where I can get 8Mbps or more as it works on a ratio system and everyone seeds.
The other thing to consider, is that a lot of ISP's are pissed off with people using torrents (basically because the ISP will sell "20Mbps" of bandwidth to you, but if you use it, they are running your service at a loss unless they are charging upwards of £120 per month lol) and are therefore starting to throttle ports, and even going as far as actually shaping your traffic and net usage to how they like it.
Imho, they shouldnt be able to do this, they say 20Mbps for instance and this is what they should provide, if they cant then they shouldnt be advertising it, but they will get away with it as Ofcom only go after Sky for anything, even TalkTalk get away with all their shit, and the problem is only set to get worse, they rekon by the end of 2008, there will be very few ISP who don't forcibly "shape" your traffic.
