htb and priorizing class

Linux Advanced Routing and Traffic Control

Hi!
I'm testing tc and htb.

In my test prio doesn't act like doc (htb manual) explains.

In particular I set 3 subclass htb each having rate 33Mbit, ceil 100Mbit. I 
also set a class having 100Mbit like parent of these 3 subclasses.

If only 2 classes use bandwidth I note that total bandwidth is equally shared 
between these (and it's right). If I set different priority of these classes 
and run the same test, transfer rate doesn't change: classes use about the 
same bandwidth (it's wrong, I think).

Because of the manual explains that if classes prio is the same, excess 
bandwidth is distributed according to rate ratios, I change rate of 3 
subclasses in this way:
class A:  70 Mbit
class B:  20 Mbit
class C:  10 Mbit

one again, if B doesn't use his bandwidth, A and C use the same rate (not 
according to their rates!)

Is this a configuration problem?

Also, when I set tc rules I get: "quantum of class xxxx is big. Consider r2q 
change"

Thanks to all,
Fabio
