A couple of things to try:

	1.  Increase the value of the kernel parameter 'nbuf' (number of 
	    file system buffers).

	2.  If this is a cluster server, increase the number of cluster
	    server processes.  The can be accomplished at boot time with
	    /etc/clusterconf or at run time with '/etc/csp -a'.

I have no specific data on HP-UX 7.05 and NFS.
