DEC sells a package which does runtime profiling of code.  It is
called VAX Software Performance Monitor, or VAX SPM for short.  It
allows program tuning based on either clock-driven sampling, or
trace-driven sampling.  In addition, the package can help with system 
tuning and accounting.
  I have used the programing tuning portion, and was satisfied, but
felt that it would not be useful until the final stages of
programming.  The system tuning portion of the package provides 
interesting data on how your system runs.  The big deficency here is 
that is does not appear to acknowledge the fact that we have eagles, 
so we can not get a realistic IO estimate from it.  This seems to be 
because the eagles are on a massbus adaptor.
