That was exactly the symptom I saw with the 3COM cards; when I switched to the EE/Pros and the fxp driver, I was able to bump my NFS blocksize to 32K. Are you dropping packets on both NICs, or just one? Make sure your NICs and your switch agree on half/full duplex negotiating. If one end thinks it's full, and the other end thinks it's half, you might have collisions that never get retransmitted. Also, try moving the cards to different slots in the MB. I think the EE/Pro cards need busmastering PCI slots (a pII/333 motherboard should have 100% busmastering slots, but you never know). -Dan Nelson dnelson@emsphone.com To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-questions" in the body of the message
