18:12:52 kernel HTB init, kernel part version 3.10
18:12:52 kernel HTB: quantum of class 100001 is small. Consider r2q change.
18:12:52 kernel HTB: quantum of class 100002 is small. Consider r2q change.
18:12:52 kernel HTB: quantum of class 100003 is small. Consider r2q change.
18:12:52 kernel HTB: quantum of class 100004 is small. Consider r2q change.
18:12:53 kernel HTB: quantum of class 100005 is small. Consider r2q change.
18:12:53 kernel HTB: quantum of class 100006 is small. Consider r2q change.
18:12:53 kernel HTB: quantum of class 100007 is small. Consider r2q change.

I get this in my logs . I tried to specify another r2q But i did not succed. Can anyone help me please?

Here's my script:

tc qdisc add dev eth1 root handle 10: htb
tc class add dev eth1 parent 10: classid 10:10 htb rate 125kbit ceil 125kbit burst 1k

tc class add dev eth1 parent 10:10 classid 10:1 htb rate 18kbit ceil 125kbit prio 2 burst 1k
tc qdisc add dev eth1 parent 10:1 handle 1: sfq perturb 10
tc filter add dev eth1 parent 10: protocol ip handle 1 fw classid 10:1
tc filter add dev eth1 parent 10: protocol ip prio 2 u32 match ip src 192.168.1.1 flowid 10:1
tc filter add dev eth1 parent 10: protocol ip prio 3 u32 match ip dst 192.168.1.1 flowid 10:1

tc class add dev eth1 parent 10:10 classid 10:2 htb rate 18kbit ceil 125kbit prio 2 burst 1k
tc qdisc add dev eth1 parent 10:2 handle 2: sfq perturb 10
tc filter add dev eth1 parent 10: protocol ip handle 1 fw classid 10:1
tc filter add dev eth1 parent 10: protocol ip prio 2 u32 match ip src 192.168.1.2 flowid 10:2
tc filter add dev eth1 parent 10: protocol ip prio 3 u32 match ip dst 192.168.1.2 flowid 10:2

.....

tc class add dev eth1 parent 10:10 classid 10:7 htb rate 18kbit ceil 125kbit prio 2 burst 1k
tc qdisc add dev eth1 parent 10:7 handle 7: sfq perturb 10
tc filter add dev eth1 parent 10: protocol ip handle 7 fw classid 10:7
tc filter add dev eth1 parent 10: protocol ip prio 2 u32 match ip src 192.168.1.7 flowid 10:7
tc filter add dev eth1 parent 10: protocol ip prio 3 u32 match ip dst 192.168.1.7 flowid 10:7

I have some info on the faq page on docum.org about r2q and quantum.
The rules (for each class) :
quantum = rate (in byte) / r2q
and
1500 < quantum < 60000.
