I'm getting this warning/error in /var/log/messages:
May 26 18:21:05 mail kernel: HTB: quantum of class 10010 is small. Consider r2q change.
Its a big deal? What should I do?
If I understand the source, that message occours when you have a leaf class whose calculated quantum (rate/r2q) is less than 1000 byte and the kernel set the quantum to 1000 byte.
I've read that the quantum should be bigger than the MTU so I don't understand why the kernel don't use a minimum quantum value bigger than 1500. Someone has a clue?
From kernel-source-2.6.10/net/sched/sch_htb.c
if (!hopt->quantum && cl->un.leaf.quantum < 1000) {
printk(KERN_WARNING "HTB: quantum of class %X is small. Consider r2q change.\n", cl->classid);
cl->un.leaf.quantum = 1000;
