Setting Virtual Processors and Memory
You can configure processor settings for a virtual machine, including the number of processors,
the amount of virtual memory available, and whether to enable hypervisor applications, code
profiling applications, and IOMMU.
Set the Number of Virtual Processors
You can increase performance of a virtual machine by making more processors available because
more tasks can be performed simultaneously. When you assign a virtual processor to the virtual
machine, it reduces the processor resources that are available to your Mac.
For Windows virtual machines running mostly office and Internet productivity applications, using
multiple virtual processors is not beneficial, so the default single virtual processor is ideal. For
server workloads and compute-intensive applications, adding extra virtual processors may
provide an increase in application performance.
Application
Recommended number of processors
Desktop applications 1 processor
Server operating systems 2 processors
Video encoding, modeling, and scientific 4 processors
In some circumstances, adding additional processors can decrease the overall performance of
the virtual machine and your Mac. This can occur if the operating system or application is not
using the processors efficiently. In this case, reducing the number of processors is recommended.
Assigning all processors on the Mac to the virtual machine results in extremely poor
performance. macOS must continue to perform background tasks even if no Mac applications are
running. If you assign all processors to a virtual machine, this prevents important Mac tasks from
being completed.
Prerequisites
Shut down or power off the virtual machine. You cannot change the setting while the virtual
machine is powered on or suspended.
Procedure
1 Select Window > Virtual Machine Library.
2 Select a virtual machine in the Virtual Machine Library window and click Settings.
3 Under System Settings in the Settings window, click Processors & Memory.
