BFQ + irqbalance... redundant?

I am currently running a kernel with BFS/BFQ and I'm wondering if running IRQBalance also is redundant, or if BFQ does not handle IRQ balancing.

Would it be wise to run both at the same time?

(I Googled around and couldn't find a definite answer.)

Re: BFQ + irqbalance... redundant?

BFQ is a i/o scheduler

BFS is a cpu scheduler

irqbalance is responsible for "distribut[ing] hardware interrupts across processors on a multiprocessor system"

from my understanding - it's not redundant at all

short answer: run it

cat /proc/interrrupts

If the kernel is already "balancing" the IRQs across CPUs, then there's no need to run a program to do it.
