***********************************************************
Pls set the default value of some parameter listed below.This will help in performance improvement
This can be set by the command /usr/kernel/sample/vmtune
-f minfree 120xN(default) if 4 cpu it is 480
-F maxfree 128xN (default) 512
-R = maxfree -minfree =32
-P min perm 5
-p macperm 10
-s 1
-b 200
-B 800
This entry u have to put in the /etc/rc before the mount all command...
