Well, we are trying to take a hard look at the shaping part of the problem (the largest user of the softirq interrupt in this case) - with "cake". http://www.bufferbloat.net/projects/codel/wiki/Cake 0) HFSC often seems like black magic to me. 1) Although I have patches for cake for linux 4.0 and later, we have not pushed them yet. 2) cake's integral shaper is somewhat aimed at improving shaping performance on very low power home routers, but it is my hope that the codebase would outperform htb+fq_codel or hfsc+fq at very high rates also. (and also be much easier to profile to improve) I would be pleased with benchmark results in your high speed environment. Cake is still very much in "what are the issues? how can we design something better than what we have?" mode, so please play with it and get back to us. -- To unsubscribe from this list: send the line "unsubscribe lartc" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
