Stef Coene, thank you for your feed-back. I have already read docum.org... The tests proved a difference of max 20Kbps between theory and real life for cbq. In my case practically nobody is limited... In my scripts there are classes with prio 8... you say max is 7... could this be the problem? Could it be possible that on hard traffic cbq to just let pass packets? This is a stupid question I guess... Do I have a chance solving the problem by swtching to HTB? This is what MRTG says about one of my 14.4Kbps clients :-) Max In 234.4 kb/s (2.3%) Average In 76.0 kb/s (0.8%) Current In 872.0 b/s (0.0%) Any opinion on 'Traffic Shaper'? I'm considering changing the shaping tool...

Prio for filters is used to order the filters. Filters with lower prio are checked first. Prio for a class is something else. A class with a lower prio is allowed to send data first before the other classes. And prio 7 is the biggest prio you can specify. I found no errors in your tc rules.
