Huh?

I don't get this.. Everyone but me appears to have problems writing to
Solaris NFS server!

I get:

-------Sequential Output-------- ---Sequential Input--

360.6 12.5

(1) is a 333/MHZ PII/SMP
(2) is a 400/MHZ PII
(3) is a 400/MHZ PII

Also, the fs that it is writing to is a raid0 array spread across 18
drives..

Now, the one thing I did on the solaris box, was to edit
/etc/init.d/nfs.server, and change the number of NFS server threads to
64. The default (4) is way, way too low..

I'm planning on trying the v3 patches, but not for at least a week..
