Hi, Recently I met a problem on different scheduler behavior between 2.4.22 and 2.6.18.8. The application works as a proxy, it listen on an interface, connect through another interface. This application works on a box with two Xeon cpu, each of them is hyper-threading. On 2.4.22, CPU0 serve interrupts, the application works on other three CPUs. But on 2.6.18.8, if I turn on 'noirqbalance' kernel parameter, and no irqbalance process, the application will stuck to CPU0 as well as interrupts after several seconds' working. Then there will be a 0% idle cpu, and three 100%idle CPUs.
/proc/interrupt shows all eths's interrupts are working at CPU0. It seems that scheduler ignores the working load of interrupts. My question is, is there a way to tune 2.6 kernel working as 2.4? Just one cpu for interrupts, other three cpu for normal work. -- wonvoo - 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
