I have also tested the examples at http://linux-tc-notes.sourceforge.net/tc/doc/sch_hfsc.txt in two different labs (both virtuals, I must say) and have not managed to see the expected latency results.
I think I can ask it in an easier way. With the configuration below I get far more delay on 192.168.10.0/24 traffic than on 192.168.20.0/24 traffic. Am I doing something wrong? If you think it is better to ask for support somewhere else and you know where, I'd be grateful if you let me know.
