  As someone already recommended, try using network cards which have 
good drivers. e1000 is probably one of those cards. The keyword is NAPI 
(or some kind of driver-dependant interrupt mitigation). For example 
the sk98lin driver you're using for eth1 has some kind of interrupt 
mitigation, however it's not enabled by default - take a look at the 
driver documentation to find out how you could set it up to lower the 
interrupt rate the card is generating.
