No user slowdown is being reported. I suspect I could use another cpu. How
can I prove that a cpu will help?
Its a 4100 5/533 running Oracle 7.3.3.6
 

The Answer is :

 
  After skimming through the OpenVMS performance documentation, please
  contact the Compaq Customer Support Center for assistance in determining
  the current OpenVMS Alpha system performance baseline and in determing
  what (if any) upgrade path is the most appropriate for your environment.
  The addition of a CPU may or may not be appropriate here, and may or may
  not result in a performance improvement, and may or may not be permitted
  by the existing system configuration.
