Hello,
is this output, normal? I meant, why counters on CPU1 is zero? Isn't this
balanced?
$ cat /proc/interrupts
CPU0 CPU1

1: 8060 0 IO-APIC-edge i8042
7: 0 0 IO-APIC-edge parport0

yes, it is normal.
If you had an interrupt-limited workload then irqbalance
would pick things up and spread them out.
