+ help
+ 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 them to a single unique cpu, so that load is
+ spread as much as possible over an entire processor set, while
+ minimizing cache hit rates for irq handlers.
