CPU_POWER_THRSH_(D)

   On Integrity servers, CPU_POWER_THRSH is a parameter expressed
   as a percentage. OpenVMS Integrity servers monitors how active
   each CPU is over a fixed time period. If CPU_POWER_MGMT is on
   and a CPU is idle for a period of time indicated by CPU_POWER_
   THRSH, the CPU is placed in a low-power mode if it is idle. A CPU
   returns to normal power when it receives an interrupt.

   For systems supporting real-time operations that require quick
   response time, VSI recommends that this feature be turned off. Use
   of this feature can result in a small performance degradation.

   For more information, see the Intel IA-64 Architecture Software
   Developer's Manual, Volume 2: IA-64 System Architecture.
