Hi Doron,


 
  Two things. One, get the latest nfs server for Linux. It's somewhere on
ftp.funet.fi hmmm, I think it's on /pub/linux/kernel/net-source/base/nfs

(also on ftp.tau.ac.il in /pub/OS/linux/kernel/net-source/base/nfs I
think, I can't remember if it's linux or Linux).

Then, add a these two optimization flags in the mount options:

rsize=8192,wsize=8192


See what happens then.

(btw, get 2.0.32, just in order to fix the other stuff, like immunity fro
the teardrop attack and from the Pentium "F0" bug).
