The download speed of Bittorrent depends on many things: seed, peer, tracker, your ISP, etc.... and no matter what Bittorrent client u are using, u will not get the maximum of your actual download speed caused this is p2p

. From my experience, BitComet seems to download very fast but Azureus has a better GUI

. So I recommend u use both of them, oh and Bittornado is also a good choice
