Our current favorite card is the intel i82559-based fxp cards. They handle the load best on our testing of 100M cards. Remember that our load is large and small packets and that hardware checksums are not a win (although hardware vlans are). So... I need to know what GigE chipsets I should test. I recently tested Intel GigE cards ... with dismal results... less than half the packets-per-second on the (otherwise) same hardware. Small packets (as in DOS attacks) are a real concern here. I believe that someone here recomended Tigon III based cards ... but I was recently looking through 5.0-RELEASE's hardware notes and couldn't find any mention of Tigon III. A hint on where to buy the cards may be helpful _and_ I'd like to know if the choice might be different for -STABLE (as some of our routers run -STABLE).
