OK You could try : ethtool -C eth0 tx-usecs 200 tx-frames 100 tx-frames-irq 100 ethtool -C eth1 tx-usecs 200 tx-frames 100 tx-frames-irq 100 (to reduce tx completion irqs) Before buying multiqueue devices, you also could try net-next-2.6 kernel, because RPS (Remote Packet Steering) is in. In your setup, this might help a bit, distribute the packets to all cpus, with appropriate cache handling. -- To unsubscribe from this list: send the line "unsubscribe netdev" in the body of a message to majordomo@...r.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
