This is not exactly numbers, but I knwo for example that a P3 Linux box 
which does not use any form of polling or interrupt mitigation will die 
of interrupt livelock if you try to route 100 base T worth of traffic 
but will route them without issue if you use some sort of interrupt 
mitigation.

So, yes, I would guess interrupt overhead IS siginifact.
