  The terse typical I/O rate dept 
 The Question is:
 
WE ARE EXPERIENCING VERY HIGH I/O, WHAT ARE THE NORMAL SYSTEM PERCENTAGES FOR
 VMS 7.1?
 
 
 The Answer is:
 
  There are no normal percentages for I/O, as attributes such as I/O
  rates are extremely implementation-dependent.
 
  High I/O rates may or may not indicate a problem exists.
 
  For information on identifying constraints and tuning OpenVMS, please
  see the OpenVMS performance management guide.  This guide is part of
  the OpenVMS documentation set, and provides a systematic approach to
  tracking performance-relevent activity, identifying constraints, and
  the necessarily associated change-testing and monitoring techniques.
