Tuning a Multi-Process Application

[Scott Guthery]

We've got a system consisting of 80K lines of Common Lisp, 60K lines of NeWS, 
and 100K lines of C & Fortran running (?) on SunOS4.0.  It's a pig.  Does
anyone know of any Unix system-wide profiling, monitoring, and/or tuning
tools what we could use to help us figure out why?  Does anyone know of any
Unix or Sun consultants that specialize in this sort of problem?  Please
respond directly.  
				Thanks much, Scott (guthery%asc at sdr.slb.com)
