What is irqbalance?
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.
why irqbalance is important?
The irqbalance service runs in the background and monitors CPU load every 10 seconds, moving interrupts to other CPU cores when a CPU’s load is deemed too high. This keeps the system performing well and able to handle load placed upon it by the hardware.
