Optimization Settings

On the Optimization pane of Virtual Machine Configuration, you can configure two groups of settings related to the virtual machine performance.

Adaptive Hypervisor

Select the Enabled option for Adaptive Hypervisor to automatically allocate the host computer CPU resources between the virtual machine and primary OS applications depending on what application you are working with at the moment. If the virtual machine window is in focus, the priority of this virtual machine processes will be set higher than the priority of the primary OS's processes. As a result more CPU resources will be allocated to the virtual machine. If you switch to the primary OS window - the priority of its working applications will be set higher and the CPU resources will be relocated to the primary OS. This Adaptive Hypervisor technology is useful when you use a lot of applications in the primary and guest OSs at a time and as a result lack the CPU resources.

Optimizing Performance

• Virtual machine . Select this option to allocate more physical computer memory resources to the virtual machine and its applications. Selecting this option may significantly increase the virtual machine performance; however, it may slow down the productivity of your host computer applications.
• Host computer . Select this option to allocate more memory resources to the host computer and its applications.

Power Consumption (laptops only)

This group of settings allows you to control the virtual machine power consumption if Parallels Workstation Extreme is installed on a laptop computer that is running on batteries:

• Longer battery life . If you select this option, the virtual machine power consumption will be automatically reduced to provide a longer life for the battery of your laptop.
• Better performance . If you select this option, the virtual machine and its applications will operate at the maximum possible speed. However, enabling this option may significantly reduce the battery life.
• Enable battery in virtual machine . If you enable this option, the battery status will be displayed in your virtual machine each time your laptop computer runs on batteries.
