} Perhaps you should try the DE4x5 (21140) driver rather than the tulip

I think we are getting hung up here on minor details.
Basically Linux in 2.0.x kernels and before has crap NFS performance. The
reading isn't too bad - say 20% slower than an equivalent box running Sun
Solaris 2.5.1, but the write performance is breath-takingly bad.

The 2.1.x implementation of NFS is completely different, looks likely to
be much faster, and I can't make it work at all on our boxes :-(

I'd say putting your cache on an NFS filesystem is going to give you lousy
performance under almost any circumstances. Having a Linux box as the NFS
client is going to make the performance move from lousy to completely
unacceptable.
