  OpenVMS Performance Tuning? (Quantum) 
 The Question is:
 
Here's a performance tuning question:
Quantum is the amount of time a process is allowed to run on the CPU.  Is there
 a way to measure the number of times quantum is reached?  It seems that if you
 have very CPU intensive processes running that reach quantum regularly, you
 could increase the v
alue of quantum, thus eliminating excessive overhead caused by loading and
 unloading the context of each process as it enters and leaves (then possibly
 re-enters) the CPU.
 
Are there any popular theories on valuing quantum or methods to determine
 whether a system has improved/declined in performance when
 increasing/decreasing quantum?
 
 The Answer is:
 
  OpenVMS process scheduling deals (automatically) with quantum end
  processing, and the scheduler will cause the current process to
  continue (without swapping the process context) when it is the best
  candidate.
