Packets were coming in so fast that the interrupt handler is consuming all your time. Alot of high speed network devices have special modes to prevent this from happening. (Only interrupt when a certain number of packets are in the FIFO, make sure the interrupt isn't asserted for more than x% of the time, etc). This is probably possible on 100MBit links on slow CPUs too. Which network card are you using? I don't ever want to buy one. :) -- Kevin Day toastyat_private - kevinat_private
