From what I know of irqbalance I would recommend using it in all cases
on a multi-core system. If you don't use it all IRQ request will be
handled by cpu0 which degrades performance of your system. When you use
CPU pinning you don't need it of course but I've never encountered
anyone using this on his desktop system.
