In your uTorrent or BitTorrent, when you open the options window, there are two options to look for. Look in the "Queueing" section for the maximum number of active torrents. This setting sets a cap on the maximum number of torrents that your client will let you upload/download combined at one time. So if you've set the maximum number of active torrents to 5, even if you have 30 torrents seeding, your client will only allow up to 5 of them (4 if you're downloading 1 torrent) to be actively uploading/downloading at a time.
The second option is under the bandwidth section. I generally put a maximum upload rate cap on my BitTorrent for the simple fact of if you don't cap the upload just under the throttle point, my ISP likes to use traffic shaping to make everything slow to a crawl until you disconnect your active P2P sessions.
Thanks
