Hello!
tc-htb is great because its easy, but you cannot specify an mpu.

You can specify mpu and overhead with htb - well you can with the recent 2.6 I use.

 Thats bad,
because with the mpu you can specify the physical characteristics of the
underlying connection. I have a braodband dsl-connection. I have the problem
that the proportion of small packets to big packets changes a lot. So
without specifing the mpu the connection is not to full capacity (big
packets) or the buffer of the modem will be filled (small packets).

If you can find your overhead for your dsl type then you can patch htb and tc to do it perfectly.

Have a look at the thesis on http://www.adsl-optimizer.dk/ there is a section that shows different overheads.
