Since windows 10 is an adaptation of Windows 8.1 as a base and bringing in some features of Windows 7. The SSD optimization guide for Windows 8.1 still applies for windows 10. To fully optimize your SSD with Windows 10, all you have to do are: Disable Superfetch and Prefetch. Make sure Trim is enabled. Disable drive indexing. Manage Pagefile.

Jump to • • • • Symptoms • I am not satisfied with my Mac performance when I run Parallels Desktop virtual machine (VM). • I am not satisfied with Parallels VM performance. Cause There might be multiple possible reasons for low performance, for example: • Underpowered hardware • Using an outdated Parallels Desktop version or build. • Too many resources assigned to the virtual machine.

• Multiple anti-virus programs installed. • Too many virtual machines are running. Virtual machine performance is directly related to computer's hardware resources. It is also very important to allocate even shares of hardware resources between host operating system (macOS) and guest (VM) according to the recommended system requirements of both systems.

Note: brings a new feature: CPU Usage Monitor. Look at VM window tray and CPU Usage Monitor will light up in red when CPU usage in Windows is above 70%. Click on CPU Usage monitor to see what processes in Windows use computer's CPU.

Clicking on a process name will open Windows Task Manager showing selected process: Computer's performance mostly depends on several hardware components: CPU, RAM and hard disk. While CPU cannot be replaced at hand, most of Mac computers enabled for RAM and hard disk upgrade. If your Mac uses a hard disk drive (HDD), it is highly recommended to replace the drive with a solid state one (SSD).

This is the #1 recommendation for all Mac users which gives significant performance boost to Mac at 2-3 times. Contact your local to get assistance with the disk replacement. TIP: you can check your Mac's drive type at 'System Information' report (click  > About this Mac > System Report. > Hardware > SATA/SATA Express) If you notice in Activity Monitor that your memory pressure is up to the maximum, it's time to check if your Mac allows you to do RAM replacement with higher modules capacity.

• Make sure Time Machine backup is not taking place while you’re running the virtual machine. The backup process may slow down overall system performance. Parallels Desktop Preferences • Make sure you're using the latest build for your Parallels Desktop version: • On the macOS menu bar click Parallels Desktop icon > Check for Updates. Download and install the updates if available. • Store your virtual machine within Mac HD (internal storage). Running a VM from external USB disk or NAS may significantly lower VM performance.

• Be careful running several virtual machines at once - each VM consumes considerable amount of resources and may slow down overall computer performance. Virtual Machine Configuration • Shutdown your VM > open its > switch to Hardware tab > CPU & Memory > make sure that the number of processors (CPUs) selected is not maximum (e.g. In most cases, half of total CPUs will provide optimal performance. Assigning more than a half of CPUs for the virtual machine may cause performance degradation for both Mac and VM.

• Make sure that memory allocation is within the recommended level. Similarly to processors, best practice is to assign half of Mac's total RAM.

NOTE: The amount of memory assigned to a virtual machine must be multiple of 1024 or Windows may behave inappropriately. E.g 1024, 2048, 3072 MBs and so on. • Under Advanced settings make sure that ' Parallels' hypervisor is selected. • Under Hardware > Graphics set Memory option to Auto (Recommended). NOTE: For Windows 10 virtual machines make sure that under Advanced Settings 3D acceleration is set to DirectX 10. • If your Mac uses an HDD or a FusionDrive (not SSD), make sure that the option TRIM is disabled: go to Hardware > Hard Disk 1 > Advanced Settings > uncheck Enable TRIM option. • Start you virtual machine and test performance.
