Hi,

My=20 system always complain with the warning below :
HTB: quantum of class = 10099=20 is small. Consider r2q change.

I simply do not understand=20 why...

Below my tc commands :
/sbin/tc qdisc del dev eth0=20 root
/sbin/tc qdisc add dev eth0 root handle 1 htb default = 99

/sbin/tc=20 class add dev eth0 parent 1: classid 1:2 htb rate = 128Kbit

/sbin/tc class=20 add dev eth0 parent 1:2 classid 1:10 htb rate 80Kbit ceil
128Kbit = prio=20 0
/sbin/tc qdisc add dev eth0 parent 1:10 handle 10 sfq perturb=20 10
/sbin/tc filter add dev eth0 parent 1:0 protocol ip prio 100 u32 = match=20 ip
dst ***.***.***.*** classid 1:10

/sbin/tc class add dev = eth0 parent=20 1:2 classid 1:99 htb rate 48Kbit ceil
48Kbit prio 7
/sbin/tc qdisc = add dev=20 eth0 parent 1:99 handle 99 sfq perturb 10

My default class = quantum (99)=20 is correct I guess : quantum is >
1500 (my MTU).
If = I change=20 the rate of my default class to something >=3D 79 Kbit then = it
work without=20 any warning !?!?

I am just looking for an explanation as I'm lost = here...

FYI :
# tc -V
tc utility,=20 iproute2-ss001007
# uname -r
2.4.26
# ip link sh = eth0
3:=20 eth0: <BROADCAST,MULTICAST,UP> mtu 1500 qdisc htb qlen=20 1000
link/ether 00:40:63:c9:b3:32 brd=20 ff:ff:ff:ff:ff:ff

Thanks,
Yacine.
