I wonder if somebody has got good results (accurate shaping) using 2.6.22?

I am testing with, 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?
