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.

SHOWMOUNT(8)						    BSD System Manager's Manual 					      SHOWMOUNT(8)

NAME
showmount -- show remote NFS mounts on host SYNOPSIS
showmount [-Ae36] [-a | -d] [host] DESCRIPTION
showmount shows status information about the NFS server on host. By default it prints the names of all hosts that have NFS file systems mounted on the host. See NFS: Network File System Protocol Specification, RFC 1094, Appendix A, and NFS: Network File System Version 3 Protocol Specification, Appendix I, for a detailed description of the protocol. -A Search for NFS servers advertised via Bonjour. -a List all mount points in the form: host:dirpath -d List directory paths of mount points instead of hosts. -e Show the host's exports list. -3 Use mount protocol Version 3, compatible with NFS Version 3. -6 Use only IPv6 addresses to contact servers. SEE ALSO
mount(1), mountd(8), nfsd(8), mDNSResponder(8) BUGS
The mount daemon running on the server only has an idea of the actual mounts, since the NFS server is stateless. showmount will only display the information as accurately as the mount daemon reports it. HISTORY
The showmount utility first appeared in 4.4BSD. 4th Berkeley Distribution September 26, 2010 4th Berkeley Distribution
