Huh? Do you mean a link to a Bittorrent client? The speed of torrents only depend a tiny bit on the client you use. Whatever client you use will still depend on the torrent itself. If it has significantly greater number of peers than seeds, it will be a slow download no matter what you do.
Also, the speed your torrents download at depends on a lot of factors, ie. your connection speed, whether you're using a router, whether your ports are open, whether your software firewall is blocking the ports etc.
