We have several VAXen with limited memory (8MB).  It seems to be generally
accepted that INSTALLing software SHARED/OPEN will reduce the overhead
of using that software, thereby improving system performance.  However,
by doing this, it would seem that the amount of memory available to users is
reduced, thereby forcing additional paging/swapping (and degrading system
performance).

My question:

Is there a point at which it becomes self-defeating to install software
shared/open?  If so, how can I determine where the break-even point is?
