I've just spent the last week installing and testing these virtualisation software for the purposes of running Windows 8 with Visual Studio software on my Mac Air. I want start using it more as a Mac rather than staying locked into bootcamp'ing
The results have suprised me compared to what i have read in the reviews about windows performance in these VMs.
In my real world usage i have found that:
* Parallels Trial performance is very poor, its slow and prone to freezing up for seconds. However Parallels has great integration and ease of use features
* VMware Trial performance is acceptable but also prone to regularly hanging for shorter bursts of time than parallels. I also experienced Windows 8 regularly crashing on VMWare with blue screen of death (HAL_INITIALISATION fail) after prolonged use. However integration was good. But the predictable BSOD was unacceptable.
* VirtualBox performance was remarkably fast and extremely usable, i didn't experience any hanging. However integration and ease of use features are minimal.
I would like to what others experience is, if they are different from mine. Also what kind of applications you are using. Thanks in advance
