irqbalance

[Mart Frauenlob <mart.frauenlob@chello.at>]

Hello,

I'm compiling a kernel for a smp box [1].
Now i found an option in menuconfig to activate 'irq balancing'.
I dont have an exact imagination what it does.
Is this recommended to use it on smp systems?
Also i found a debian package called 'irqbalance'.
It's a userspace daemon, erm... doing the same as the kernel option?
Or do i need to enable it in the kernel to be able to use the features 
via the userspace fronted, like it is with netfilter/iptables?

Thank you for help
