I'd expect about 1Mbit on such machine. in tc -s qdisc there is value deq_util 1/X (under load). The X should be larger than 20. If lower the qdisc is overloaded. Unfortunatel;y the value is computed using TSC which is available only on Pentium CPU .. > 2) In your latency tests I have seen that you generate traffic to > saturate link but you do not OVERLOAD it. Can you please redo your > simulation with more traffic? The link WAS overloaded during the test. You can't see it from graphs as there is only already shaped figure .. But I just finished new algorithm implementation and will rerun all test with it. I'll focus on this part. devik
