hm. I need to update some of those numbers. ssh on a 486/66 is painful, as is 16M RAM. :) > It's a very old article but they say that "Realtek 8139 are reported to > beat up the processor badly".

However, "good" means "works". That isn't to say this card is any kind of screaming performer...but it works. You are generally going to have to move a lot of packets before the issues of the Realtek chip hurt you on modern hardware. Put a Realtek card in a Pentium 75MHz machine, you may wish you didn't (or maybe it would work fine...haven't tried, actually). Throwing away a Realtek card in favor of a 3c905 seems to be completely pointless. The 3c905 is overrated. They are a sub-standard card on all OSs I've used 'em on. For 100Mbps cards, I'm partial to fxp(4) (Intel) and 21143 (dc) cards. Unfortunately, 21143 cards seem to be almost impossible to acquire through my usual channels. My gigabit experience is too limited to comment upon. Nick.
