you can't really use altq well where you don't know the connection speed. to work properly when the line is full, you need to restrict it to the lowest speed your connection might be running at, and take into account any other users (unless all traffic on the line is going through this box). there are some other things that might apply: - there may be a disconnect between incoming and outgoing traffic, maybe the proxy fetches the object at whatever speed it can and buffers it - you might not want to throttle sending cached objects to the lan, only the internet bandwidth - altq only restricts the speed of outbound traffic altq running on the proxy may well not be the correct tool for the job here. maybe squid connection pools, or something else, are more appropriate. or maybe altq on another machine/cluster (e.g. a firewall) sitting between the router and the entire network might be a good choice.
