Hello!

I have a problem with i detalied in an = early mail=20 but there was no answer so i will try to be more specific.

i have this

tc class add dev eth0 parent 1: classid = 1:1 htb=20 rate 64kbit ceil 256kbit burst 15k quantum 1500

tc class add dev eth0 parent 1:1 = classid 1:100 htb=20 rate 32kbit ceil 256kbit burst 15k
tc qdisc add = dev eth0=20 parent 1:100 handle 100: sfq perturb 5 quantum 1500

tc class add dev eth0 parent 1:100 classid 1:1001 htb rate 8kbit = ceil=20 64kbit prio 5 quantum 1500 burst=20 15k
tc qdisc add dev eth0 parent 1:1001 = handle 1001:=20 sfq perturb 5 quantum 1500

when i add more clients for the class 1:100 and i start the = script=20 problems such as request timeout and verry slow speed (0,5kbps) = appear

where is the problem... ? is the burst too big? how should it be = set?

the perturb is too small?

i used SFQ... each queue should have her turn once in a while... if = i send=20 10 ping requests from a host at least 2 of them are timeouts... = why?

i am stuck please help.

Claudiu.
