Many thanks to those that replied with suggestions. It turns out to be a
bug in the NetApp software version that I am running.
The Solaris 9 machine that worked great was reverse dns'ed. The Solaris 8
machines were not. Since they were not reverse dns'ed the netapp was
failing with a gethostbyaddr call and thus causing the slowness. The
solaris 8 and 9 differences caused me to go down the wrong path, but
eventually truth prevailed.
The work around is to reverse dns the servers or add them to /etc/hosts file
on the filer itself. They have also fixed something to prevent this in a
later release of the software.
Once again,
many thanks
Ryan

Subject: Weird NFS performance problems on solaris 8 and netapp
I recently installed 2 Sun V210 servers (Solaris 8 HW4 update) with 1 week
old patch recommended cluster. I am noticing painfully slow nfs performance
to a volume mounted to a NetApp filer. When I try to access the same netapp
volume from a Solaris 9 machine (Sun 220R with Solaris 9 U7 and 1 week old
patch cluster) I see great performance.
Where am I going wrong or what can I begin to check?
I have hard coded the /dev/bge0 settings and cisco switch to match as
follows
ndd -set /dev/bge0 adv_1000fdx_cap 0
ndd -set /dev/bge0 adv_1000hdx_cap 0
ndd -set /dev/bge0 adv_100fdx_cap 1
ndd -set /dev/bge0 adv_100hdx_cap 0
ndd -set /dev/bge0 adv_10fdx_cap 0
ndd -set /dev/bge0 adv_10hdx_cap 0
ndd -set /dev/bge0 adv_autoneg_cap 0
