I did some "stream" tests with htb. I generated a lot of tcp traffic with tcp
and recorded the shaped bandwidth. The result is allmost perfect. (results
can be found on www.docum.org on the test pages).
But in a real world scenario, you also have bursts in the traffic. Maybe you
allow bursts (you always have some minimal bursts) so the average bandwidth
may be higher then the configured bandwith.
