Solaris NFS Client Settings?

[Tim Evans <tkevans tkevans com>]

We're having trouble with performance of Solaris 9 NFS clients to RHEL 3 
servers. I've seen the HOWTO at:

http://nfs.sourceforge.net/nfs-howto/interop.html

It addresses for the most part the reverse situation (Solaris server, Linux 
client), however.

Under any kind of load, the Solaris clients whine about the mount coming and 
going, and write performance is abysmal.  We've tried default NFS mounts (i.e., 
no options). Also, some searches turned up various recommendations, that are 
shown in the Solaris client's /etc/vfstab entry below:

server:/data1     -       /data1  nfs     -       yes     
retry=3,rsize=1024,wsize=1024,vers=3

None of these seem to make any difference, though.

Anyone have working options for this situation?  Thanks.
