htb_sched structures are big, and source of false sharing on SMP. Every time a packet is queued or dequeue, many cache lines must be touched because structures are not lay out properly. By carefully splitting htb_sched in two parts, and define sub structures to increase data locality, we can improve performance dramatically on SMP. New htb_prio structure can also be used in htb_class to increase data locality. I got 26 % performance increase on a 24 threads machine, with 200 concurrent netperf in TCP_RR mode, using a HTB hierarchy of 4 classes.
