No, for public torrents that sounds right. But you may see some improvement but not much, record I've seen for a public torrent is 500kb/sec and that was for a 100mb tv serie ep... On private I easily max out my connection though.
Try to get into a good private torrent site if you want normal speeds.
Also have you set your max upload to about 70% of what it does when unlimited? High upload really really limits your dl speed.
Oh and Nabz, blanc out the download names, a lot of anti pirate whiners on this forum

, if they see that pic they will come after you with their keyboards

Thats rubbish unless he's using a silly low amount of max connections, with public the rule is generally the more you add the faster your total download speed is...
