Hi all,

 I have a problem with htb and wonder if anybody has encountered this.
 On my LAN I have more than 1000 clients, and I am using htb to shape the incoming trafic. The problem is that I am experiencing packet loss (about 4%) in the qos server.  The server is droping packets even if my trafic is relatively moderate.

 I tried everithing estimator, senting the quantum etc etc but it doesn't seem to improve.

 my script is relatively simple:

 tc qdisc del dev eth0 root
 tc qdisc add dev eth0 root handle 1: htb default 10

 #root class
 tc class add dev eth0 parent 1:0 classid 1:1 htb rate 50000kbit ceil 50000kbit
 #default class
 tc class add dev eth0 parent 1:1 classid 1:10 htb rate 512kbit ceil 512kbit

 #and each client IP has a class asocieted 
 tc class add dev eth0 parent 1:1 classid 1:$COUNTER htb rate 5kbit ceil 400kbit
 tc filter add dev eth0protocol ip parent 1:0 prio 2 u32 match ip dst $IP flowid 1:$COUNTER
 # and counter increments by 1 for each rule added

 What could I do ? Are there some kernel parameters that I could modify in order to obtain a better performance ? 
 Thanks
