I am not so sure with that 6% difference there is no other bug lurking there; 6% seems too large for an extra two PCI transactions per packet. If someone could test a different NIC this would be great. Actually what would be even better is to go something like 20kpps, 50kpps, 80 kpps, 100kpps and 140 kpps and see what we get. cheers, jamal - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
