How do I get faster torrent download speeds?

[2bad]

I'm using BitTorrent 6.1.2 to download torrents, but it just takes SOOOO long...My download speed is at MOST 5 kB/s with three torrents running. Should I switch clients? I used this guide to change my prefrences:
http://torrentfreak.com/optimize-your-bittorrent-download-speed/
but it really did nothing...Is there a way I can download quickly without seeding, and then seed overnight? thanks

I realize it depends on how many seeders and leechers there are....most of the ones I get are about 1:1.....still shouldn't be having speeds like that should I?

You can try right clicking on the torrent inside bit torrent and set bandwidth level to high, but I don't think that'll do much.
