Unfortunately I had to disable 3D acceleration for the Virtualbox tests, when it was turned on PCMark would crash for me right after starting. I could probably have tested some Linux / Mac operating system startup performance, but that would have increased my test time more than I would have wanted – maybe next time. Hence I assume they somehow change and enhance the bootup process to get this clear advantage. How come ? Well Virtualbox and VMWare show the normal boot screen just like a regular PC for Windows 7 ( the three moving colory things), while Parallels shows some Vista style progress bar. However I assume they use some startup optimization by modifying the windows boot process. In Windows 7 Startup performance the clear winner in my tests was Parallels Desktop. Taken was the time from pressing the "Start VM" button until the Desktop background first appeared, this means these times include startup and initialization of the VMs and it's bios. Windows startup performance was measured with a stopwatch, taken 7 times, best and worst time were thrown away and the other times averaged for each product. Each virtual machine was installed with standard options, given 2GB of RAM and 20 GB of dynamically expanding harddisk. Tested product versions were : Virtualbox 4.1.6, VMWare Fusion 4.1.1 and Parallels 2. No additional software was installed on the machine, just bare Mac OS + one of the virtualization software products. And waited at min 1 Minute after Startup to ensure all system services and startup items were done. I installed each of the three on a fresh installation of Mac OS X (10.7.2), rebooted between startup tests and bechmarks to avoid caching effects. The tests were conducted on a MacMini 2011 with 2,3 GHz Core i5 Processor and 8 GB RAM and the Stock 500GB Toshiba MK5065GSFX HardDrive. Installed the three and made some testing and benchmarks. Fortunately VMWare and Parallels provide time-limited demos of their software for evaluation purposes. It proved to be hard to find some serious comparison of the three at a recent version. Parallels and VMWare are commercial products while Virtualbox (at least the main part) is now OpenSource and if you use their Oracle Expansion Pack is at least free for personal use under their PUEL License). Virtualbox (OpenSource / with Extension pack usage under their PUEL License).VMWare Fusion (~ 70 €, now 40 € introduction price).I see three main competitors for Desktop Virtualization on the Mac: uhh software.I recently needed to decide which virtualization software to use on my new MacMini. Expect way more that from a commercial grade product who expects money for their. Just more than had it vmwares incompetence. I'm switching all my VMs to KVM before the end of the month. The host is not lagging at all, plenty of free RAM, plenty of free disk, just don't understand what the f*ck vmwares problem isīut yeah I'd probly say it's a good time to jump off the vmware train. The lag is sooo incredibly unbearable at times, you can't even see what you're typing. There are some threads online but they just suggest disabling 3D (not an option, this is a laptop-CPU is going to ravage my battery.) (16.2.x) Everything used to work great with 0 lag under 16.1.2 (as a few others have suggested), the few updates that have come since, have failed to address this issue to any degree. There is currently something ugly happening with 3d accel/input lag for tons of people. Been using VMware workstation pro for a long time now, years, across a few hosts.
