Sorry if this is mildly off-topic...

I've been testing throughput on a CARP setup using old hardware and a 
bunch of fxp (82557) cards.  I've noticed that traffic halts once 
interrupt traps hit between 18k-20k (note, this has nothing to do with 
CARP, it's the effect of passing packets across dual homed).  Would it 
be feasible to expect that the em gigE cards will handle this load?

Thanks,
