<div>doesnt have CEIL defined? it has to have it defined so your modem wont queue packets, making your latency go to meet the sky :-) set it to 90-95% of the bandwidth your modem can do</div>

<div>put some leaf qdisc like SFQ.</div>
<div>/sbin/tc qdisc add sfq parent id 2:20 handle 20 : sfq perturb 10</div>
<div> </div>
<div>5. performance fix</div>
<div>in the classes 2:10 and 2:20 you're using only 256kbit of RATE. change it so their sum is the rate of their parent. <br> </div>
