Do you think this "anomaly" might be a consequence not choosing
the average size correctly? Have you done some tests with a higher avgpkt value?


I suppose CBQ does packet per packet handling, assuming the average packet size is what you specified on the command line. But what if the
real average packet size is bigger?

I just did the tests and these are my results : (I use ttcp to test)
for class 20:1 = 71.90 KB/sec (575.2Kbit/sec)
for class 20:2 = 134.05 KB/sec (1072.4Kbit/s)

The numbers are not correct, but I think it's just CBQ that's not very
accurate when you use the bounded paramter.  I got the same results when
I use everywhere prio8 and put class 20:2 on qdisc 20:0.  So it's a CBQ
accuracy problem.
