The Optimization page allows you to specify settings that will be used to optimize Windows running in guest VMs for best performance in a Parallels RAS environment. You can select Windows components, services, and other options that will be disabled, removed, or optimized to ensure a more efficient, streamlined, and improved delivery of virtual apps and desktops. For the complete description, please see Optimization.

After reading the Optimization section mentioned above, please also note the following VDI specifics:

  • Optimization is disabled by default when you create a new template. If you plan to enable it, you should make a backup (create a full clone) of the source guest VM before doing so. You can also create a template with optimization disabled, then create a snapshot, and only then enable optimization. Making a backup is a good idea because once optimization settings are applied, they cannot be rolled back.
  • To enable optimization for an existing template, the template must be in maintenance. A template in the "Ready" state has the Optimization tab disabled.
  • When optimization is enabled or modified for an existing template and the template exits the maintenance mode, the administrator will be asked to recreate existing guest VMs, so that optimization settings are applied to them. Note that guest VMs must be recreated (now or later) to receive optimization settings.
  • When optimization is applied to a template, its status changes to Optimization in progress (among others). At this stage, you can select the template in the list and click Tasks > Stop optimization, which will cancel the operation.
