But the 3C59x cards are architecturally crappy. I doubt the 3C9xx ones are much better, despite of all marketing hype. 3Com went the route to continously reduce the available buffer size. I've heard that they're shipping cards with as few as 8 KB FIFO, so that you are forced to use 6 KB Rx FIFO, and 2 KB Tx FIFO. This means that a back-to-back stream of an 8 KB NFS block won't fit right into the FIFO, and requires CPU interaction shortly after the first packet came in. Nothing i would recommend to the people, even though FreeBSD's driver has been improved recently. -- cheers, J"org joerg_wunsch@uriah.heep.sax.de -- http://www.sax.de/~joerg/ -- NIC: JW11-RIPE Never trust an operating system you don't have sources for. ;-)
