High interrupts

sioren

Hi!

i configured the latest pfsense 2.7.0 release on a Sophos XG 106.

vmstat -i shows this output:

interrupt                             total               rate
irq4: uart0                          227                 0

irq137: igb2:aq                   4                    0
Total                                   47492585      739

Which interrupts value is normal, what can I do against it?

Thanks!

That looks normal. It's the interrupt rate that counts and none of those are very high. The total interrupts just increase with uptime/traffic.
