Virtual Machine Management
Most users will probably have just a single virtual machine to deal with. But if you manage multiple VMs and switch them frequently, the time it takes to boot, suspend, resume, and shut them down can be important from a productivity standpoint. We’ve therefore looked at how quickly the latest versions of Parallels, Fusion, and VirtualBox handle these operations. Each task was performed five times, and the results were averaged and rounded to the nearest tenth of a second. The chart below shows those results in seconds, with shorter bars meaning faster performance.
When it comes to a Windows 7 VM, Parallels has the fastest management times across the board, with its most significant lead in terms of cold boot times. All virtualization platforms can suspend a VM nearly equally fast, although VirtualBox struggles against the competition when it comes to boot and shutdown times.
While these results are interesting, only those who frequently switch VMs will likely care, and a user already committed to a particular platform probably won’t, or shouldn’t, be persuaded to switch based on a few extra seconds when booting or resuming a VM. After all, the largest disparity on this chart is the 9.2-second difference in shutdown times between VirtualBox and Parallels 10.
