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 ? Currently my problem is that i have too big system load over CPU / 60-80%/ and packet dropping. at every 15-20sec i have traffic freeze for 1-2sec. when more users are online.

In general the dual core Opterons tend to be a lot faster than the P4 dual cores. But its possible that this has changed since I last saw a performance comparison of the two. -Paul On 1/30/06, foxy 202 <foxy202@gmail.com> wrote:> > > 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.

At least it works for me. However, if you start using tcpdump, your CPU usage will go through the roof. Suggestion: Use oprofile and find out what demands the most performance in your setup, then fix that and retest. Regards, Carl-Daniel -- http://www.hailfinger.org/

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 ?
