I was recommended uTorrent last year and have been using it since. I was generally pleased with it - my two issues being that when it was on then I couldn't open new sockets - no new SSH connections, no reading web pages, no starting up the daemon that's part of my current project.
I accepted this. I presumed it was because, somehow, it used up MAX_SOCKETS or whatever. Either way there seemed to be nothing in the FAQs about it so either it was unreproducible (whihc seemed unlikely) or it just was. But it was fine. I'd just run it at night. However, what was more annoying was the fact that someitmes it would run for hours. I could leave it running Friday night, get back Sunday evening and it would still be running. Other times however, and this was far more frequent than running for hours, suddenly all download pseed would drop to zero. And stay that way. Restarting it usually helped but often it would get itno a spiral. The 'uptime' would get less and less and less until it was unusable and I'd tend to reboot my machine and also cycle the router because, well, voodoo sometimes works. Again, nothing in the FAQ. I guessed it was a Windows issue - maybe resource starvation or something. Sockets not being freed. Annoying but plausible. Then someone reccomended Azeureus to me. They'd never heard of these problems they said. So I gave it a try. Oh my! First off - I can surf the web and open new connections when it's on. Hurrah! Ok, so someitmes it can be a bit laggy but I dpn't mind because ... It seems to be about twice as fast. I don't know if that's me ascribing all kinds of wonderful to it but I swear it seems to be getting the same torrents I was downloading with uTorrent at double the download rate. Which is good because I need that, err, iso of Debian right now. *cough* And it hasn't stopped downloading at all. Rarrrr! So, in summary uTorrent == the suck Azeureus == t3h w1N!!!!1111
