I'll read it now ;-)

Yes, I had already tried this.  Since I installed kernel 2.6.0 however, the 
performance has degraded *much* further - to the point where I'm lucky to get 
300kB/sec over NFS, whereas FTP easily reaches 7MB/sec!!!  I found that 
setting rsize+wsize to 2048 improves it enough to be workable (2MB/sec) but 
I'm still not sure why a kernel 2.6.0 client has so much trouble talking to a 
2.4.22 server (both NFSv3.)  Also, if I try to access another file on the 
same share, network traffic drops almost to a standstill and physical disk 
access stops entirely until I stop one of the processes accessing the NFS 
share - and while this is going on the system CPU % is almost as high as it 
can go, so I'm really confused about what could be causing that, but I'll 
work through the URL you sent and see if I can work it out.
