Performance optimization

CHARON takes 100% of host CPU even in case of idle state of guest OpenVMS operating system. To get rid of such resources consumption there is a specific option provided by CHARON Guest Utilities - "idle" mode.


$ CHARONCP SET IDLE /ENABLE

Loads the OpenVMS idle loop detection software. This allows CHARON to detect when the emulated CPU(s) are idle and use the host power saving instructions to reduce power usage.

$ CHARONCP SET IDLE /DISABLEUnloads the OpenVMS idle loop detection software.
