Re: P4 dual core vs AMD64 dual core with HTB

Linux Advanced Routing and Traffic Control

Hi All,

Please for some advice.

I have Linux router that do traffic control with HTB , routing and traffic
counting.
currently machine is with P4 2.2GHZ 1GB RAM. I plan to migrate to dual core
CPU. I know well
P4 dual core but is it anybody has experience with AMD64 dual core / or
single core /  for traffic control . I use Deban Linux for my router. Can I
expect problems with HTB and iproute 2 over ATHLON DUAL CORE/BOX or single
box ?

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 ?
