I wonder if somebody has got good results (accurate shaping) using 2.6.22?
I am testing with 2.6.22.1, and I haven't been able to get accurate shaping.
For instance, I tried:
$TC qdisc add dev eth0 root handle 1: htb default 1
$TC class add dev eth0 parent 1: classid 1:1 htb
rate 100000kbit ceil 100000kbit burst 24k cburst 24k
$TC class add dev eth0 parent 1:1 classid 1:10 htb
rate 20000kbit ceil 20000kbit burst 24k cburst 24k
and class 1:10 shapes the traffic to 19900kbit instead of 20000kbit
(bandwidth tests made with ftp and iperf)
That seems pretty close. What values do you get with older kernels?
