That said, most torrent clients are configurable in several ways. 1) You can limit the number of download flows to something far less than 6. Try 1 or 2. 2) You can typically rate limit them in the client to a lower rate during the day and a higher rate at night. 3) You can tell them to mark the torrents as background (QoS marking CS1), but that only helps on uploads vs the simple.qos script. At the router itself, you can try things like identifying torrent traffic via a consistent port number (if you have one) to toss it into the background queue , or try qos-scripts which has a layer 7 dpi tool.
