First, I am running RH 9 on my workstation and have a RH 7.1 box running as a webserver. I mount /home via nfs from the RH 7 box to my workstation. I have noticed that write speeds to /home are very slow, with no obvious reason. If I copy a file from /tmp (local) to /home/raymond (remote) it takes forever, and there is next to no network usage or cpu load. Transfers in the opersite direction saturate the 10MBit connection.
I am using the following options for mount: rsize=8192,wsize=8192,intr
I had this probably on a machine a couple of computers ago and I'm not sure exactly of the details but I think I had to change the wsize to something smaller and that sped things up. I think it had something to do with being compatible with the buffer size on the enet card.
I think I may have read about that in the NFS HOWTO.
Cheers Glenn, I have removed the {r,w}size from the options and using the default read and write sizes, 4096 I think. Makes a big difference to writes. The strange thing was there appeared to be no traffic on the device when it was running slow. I have been running happily with {r,w}size values of 8192 for many years. I have released now that this is the first time in many years I have been running with a Half-Duplex hub in the network. Raymond
