Slow NFS performance

Hi,

I have a network with two computers, connected through a switch. One
machine runs Radhat 9 and is an NFS server, the other machine used to
run Redhat 9 and mounted an NFS volume on the server. No problems with
that setup.

Recently I upgraded the second machine (the client) to Fedora Core 2.
Now NFS performance is really slow. I checked the connections and
noticed that other protocols do not have the problem (FTP is lightning
fast). So it has to be the NFS implementation of Fedora Core 2.

I cannot upgrade the second machine to FC2 since it requires special
hardware drivers not available for 2.6 kernels.

Strangely enough I could not find a similar problem in any mailing list.

I tried different mount options (rsize, wsize) but nothing changed. This
is what the /proc/mounts says about my NFS mount:

192.168.2.2:/mnt/media /mnt/media nfs
rw,v3,rsize=8192,wsize=8192,hard,udp,lock,addr=192.168.2.2 0 0

I hope any of you knows where to look for a solution, since this problem
makes my computing environment pretty useless.

Thanks in advance,

Philippe
