>From what I can tell thus far, the 3c905 only has 4k buffer on board. Thus, it does not handle 8k fragmented nfs packets well. Based on suggestions I installed the Intel EE card on our primary server this morning. So far it is much happier. I have used the hack that you mentioned. I believe that it will decrease NFS performance somewhat on a card that can handle 8k packets, but will greatly increase performance on a card that can't. If you want to increase your nfs read/write sizes you will need to replace your NIC cards (as I mentioned above, in our case, just replacing the card on the server seemed to make a big difference).
