Network interfaces is onboard, connected over PCI-X.
Right now i am using only one processor, cause using only one interface and interrupts stick to it. Other is almost not used.
At peak time i notice in mpstat, that this processor is almost "dead", and if i run minor application consuming resources - ping over this router will be terrible. For me it is clear - system overloaded. I did oprofile, and here is result (at low load time, but at peak time it is very similar).
Do you have any packet sockets in this system? Like running dhcp daemon?
