Have you ever tried irqbalance service? It may help to balance irq if the irq workload of 3rd cpu is too heavy. thanks, linfeng > [root@localhost ~]# cat /proc/interrupts | grep eth9 > 25: 5824 13914 159 128 210 > 0 0 0 IR-IO-APIC-fasteoi eth9 > [root@localhost ~]# cat /proc/interrupts | grep eth9 > 25: 5824 13927 159 128 210 > 0 0 0 IR-IO-APIC-fasteoi eth9 > [root@localhost ~]# cat /proc/interrupts | grep eth9 > 25: 5824 13939 159 128 210 > 0 0 0 IR-IO-APIC-fasteoi eth9 > [root@localhost ~]# cat /proc/interrupts | grep eth9 > 25: 5824 13973 159 128 210 > 0 0 0 IR-IO-APIC-fasteoi eth9 -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
