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 /DISABLE | Unloads the OpenVMS idle loop detection software. |
