Hi,
I think this is a really good question.
I'm curious since we use a lot of stripped-down FreeBSD for modest
performance routers.
We typically enabling our interfaces with POLLING not so much for
performance (it seems to be a negligible improvement nowadays) but so
that we know that
OK, I'll try to explain in another way.
While I've done network performance test I've monitored the IRQ rate,
and, for example, it's a 7000/8000 interrupts per second in every NIC (I
use 2 NICs in a bridge). The question is
¿how can I know if this irq rate is too high or not? ¿how can I know

I must say, that I did not do hardware since some time. But 10 000
Interrupts per second is not this high. Modern CPUs should be able to
handle much much more.

Dear Jordi,
In theory, on a Gigabit link you get 1 000 000 000 bits * second.
By default you have the MTU set to 1500 bytes which makes ~12 000 bits.
1 000 000 000 / 12 000 = ~ 83 333 packets per second.
