I changed the thread title - because this appears to be a solaris only question.
Anyway, are you having NFS perfomance issues? Please describe what the symptoms are.
Otherwise tweaking this parm is not going to do perceptibly very much positive. It just wastes resources, IMO. Sometimes it looks like a great idea to take a tunable kernel parm from some low number to a higher one. These kinds of adhoc changes can actually slow things down.
Does iostat show that asvc_t times are large on NFS mounts? Plus, be sure you DID NOT mount NFS drive directly off /, because if the NFS drive has problems/issues, commands like pwd and the underlying system calls may hang. They have to traverse /.
If this sounds all wrong, then, you need to explain your problem fully.

Dear all,
I have a Local zone , where users feel that performance is not good.
Is it wise to collect the inputs from the local zone rather than taking from the global zone.
And also Can I tune from Global zone , so that it will reflect in local zone.
