Irqbalance is a daemon to help balance the cpu load generated by interrupts across all of a systems cpus. Irqbalance identifies the highest volume interrupt sources, and isolates each of them to a single unique cpu, so that load is spread as much as possible over an entire processor set, while minimizing cache miss rates for irq handlers.
