I have dual core p4 (64bit compiled) with hfsc configuration for 4500users 
CPU load on this machine is about 20% Average with 60Mbit/s traffic
 

I also want to know did the AMD (Opteron) will be better for such solution like traffic management :)



>Currently my problem is that i have too big system load over CPU / 60-80%/

How many users You have ?
How many pps on interfaces ?
How large is traffic load (data) , what kind of traffic ?
Did You use hashing filters for traffic management (filtering) ?
Is this machine is doing NAT or any of iptables things ?


>and packet dropping. at every 15-20sec i have traffic freeze for 1-2sec.
>when more users are online.


What type of interfaces You have ?
Did You use NAPI if available ?
