I've been testing the adaptec 64044 card (if_sf driver) which is a 64bit 66Mhz 4 port ethernet. I can have come to one of two conclusions:
1) the card sucks 2) the driver sucks or both. A 32bit Dlink 4 port card outperforms it by a wide margin, as do 32bit eepro100s. "wide margin" being defined as about 40%. Given that bus resources are not easily measureable..Im quoting cpu usage for handling the same number of pps. But its pretty difficult to justify using a 64bit slot and rather expensive card with such lousy performance. I cant even justify the bus-bandwidth saving with a card that cant route more than 250Mb/s. I guess my question has to do with whether the board is just a dog or the driver needs substantial optimization. The folks at adaptec aren't dopes generally, so I cant imagine that they chose a chipset that was so inferior to the one on their 32bit adapter (which uses the same as the Dlink).
