NFS mount options

I am hoping that you can shed some light on this for me. I am
experiencing bad NFS performance. I do not have much experience with
this. My support engineers told me to set the "noac" option in the
/etc/vfstab file, to improve my NFS performance (after they also did
some searching on the web).

I tried Google, I tried the sysadmin guides, and cannot find examples of
how this is done. I tried it myself by just putting in in the vfstab
file, but received an error doing this.

Is this option supported in Solaris 9 ?

The line in /etc/vfstab (after I changed it):

/dev/vx/dsk/testdg/intest /dev/vx/rdsk/testdg/intest /intest ufs - yes
nolargefiles,suid,noac

The error I received:

mount /intest
mount: /dev/vx/dsk/testdg/intest on /intest - WARNING unknown options
"noac"

Any help will be appreciated
