Actually, that's interesting. higher than fq_codel Are you running fq_codel as the root qdisc? Because in that case you're running through the single qdisc lock, which could explain the difference. Try running separate fq_codel instances beneath an 'mq' qdisc as the root. Also, if you're not setting a shaping rate, cake_mq is basically the same as just installing an mq qdisc at the root and having separate cake instances beneath that. So to test the multi-core shaper algorithm you'll need to set a rate ('bandwidth' parameter). -Toke
