[LARTC] Consider r2q change, why !?

[Yacine]

Hi, My system always complain with the warning below : HTB: quantum of class 10099 is small. Consider r2q change. I simply do not understand why... Below my tc commands : /sbin/tc qdisc del dev eth0 root /sbin/tc qdisc add dev eth0 root handle 1 htb default 99 /sbin/tc class add dev eth0 parent 1: classid 1:2 htb rate 128Kbit /sbin/tc class add dev eth0 parent 1:2 classid 1:10 htb rate 80Kbit ceil 128Kbit prio 0 /sbin/tc qdisc add dev eth0 parent 1:10 handle 10 sfq perturb 10 /sbin/tc filter add dev eth0 parent 1:0 protocol ip prio 100 u32 match ip dst ***.***.***.*** classid 1:10 /sbin/tc class add dev eth0 parent 1:2 classid 1:99 htb rate 48Kbit ceil 48Kbit prio 7 /sbin/tc qdisc add dev eth0 parent 1:99 handle 99 sfq perturb 10 My default class quantum (99) is correct I guess :  quantum is > 1500 (my MTU). If I change the rate of my default class to something >= 79 Kbit then it work without any warning !?!? I am just looking for an explanation as I'm lost here... FYI : #  tc -V tc utility, iproute2-ss001007 #  uname -r 2.4.26 #  ip link sh eth0 3: eth0: <BROADCAST,MULTICAST,UP> mtu 1500 qdisc htb qlen 1000     link/ether 00:40:63:c9:b3:32 brd ff:ff:ff:ff:ff:ff Thanks, Yacine.
