Even the most efficient cards use 50%? This seems really high to me.
Arent there some good quality cards that offload a fair bit of the
processing to the card (with appropriate quality drivers) - intel eepro1000s
anygood? (They have a good reputation for fast ether cards in terms
of efficiency). Whats the most efficient GbE card?
