Speed difference between Torrent clients.

[ghostinferno]

There are tons of torrent clients out there. Fans of every client claim that their's cleint gives the fastest speed. Iuse utorrent.
I wanna ask wether these torrent clients make any difference in the downlaod speeds as the download speed, i guess, depends on the number of seeds and leechers and their internet speed.
What role does our torrent client plays in increasing the speed?

only few tweaks can get u good speed but speed increase is about 5-7kbps not more than it, all n all speed depends on Seeds + Peers & ur Internet connection
