I'm having trouble to shape traffic for a few thousand users. Every time the interface bandwidth reaches around 4~4.5gbps, CPU load goes from 10~20% to 90~100% when using HTB. For HFSC this occurs around 2gbps. I googled the problem and bumped into this topic (xdp-project) and Mr. Brouer told me about this list. Please tell me which info I can feed you to help me with this issue. I made a lots of experiences with no luck. I am not a top level expert but I learn quick. Regards Ethy
