You can't get the full bandwidth because you need to set the upload
limit at a level that can be sustained upstream in your router or modem;
otherwise it doesn't work properly. You can't just use your nominal
line-speed or let altq pick-up the interface speed.
It depends what you are trying achieve. If your sole object is to
prevent ack delays reducing tcp download speed then altq will do it.
However, if you want to seed afterwards you need to reduce the impact on
latency-sensitive protocols like http and imap. Further traffic
prioritization does help, but I find that I get better results if I
also set the client to limit itself a bit below the altq limit.
In my experience tcp limiting also produces steadier uploads than altq
so the average rate can actually be higher.
