[asterisk-users] Balancing interrupts.

[Steve Edwards]

I see the following on one of my new servers:

-ts10::sedwards:~$ ps -e | grep bal
   2633 ?        00:00:00 irqbalance

Should I be concerned that cpu1 is servicing only 700,000 interrupts from 
my te410p while cpu3 is servicing almost 90,000,000?

I thought this is what irqbalance was for...

Thanks in advance,
