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.
