Thank you.

Should IRQ's for a given network interface be distributed on all CPUs or
only be handled by one CPU? I've read a lot of stuff about kernel irq
balance (which just found out is now obsolete), smp_affinity and
irqbalance userland daemon, but I'm still confused about what should I
see in /proc/interrupts as an optimal behavior. Ar for now, I've only
been able to handle interrupts for a given NIC by one CPU.
