Exactly the scenario I want to avoid :) My setup is a bridge firewall, so two interfaces in a bridge, no userspace programs except an ssh. Correct me if I am wrong here. I believe most of the work done by my system is processing the nic interrupts and inside netfilter code. So if my system has to drop the packet it would mean that the inturrupts are coming so fast that the system cannot cope up with it. If I could determine how much time it takes to service an interrupt or at lest get an indication as to when there are some "near miss" I can avoid packet loss. regards, raj
