That may work maybe even add ipproto as a 3rd tuple; experiments will tell - you need to be able to generate a random enough traffic pattern. For example if the traffic pattern is always for your local host the dstip may not be useful to the hash. You could always try the hash tests outside first; look at some of the jenkins hashes in the kernel > __do_IRQ has a tendency to collect same IRQ on different CPUs into one CPU > when NIC is busy(by IRQ_PENDING & IRQ_INPROGRESS control skill). so, > dispatch the load to SMP here may be good thing(?). possibly. Or you may wanna tie the NIC IRQ to a CPU. cheers, jamal - To unsubscribe from this list: send the line "unsubscribe netdev" in the body of a message to [EMAIL PROTECTED] More majordomo info at http://vger.kernel.org/majordomo-info.html
