they are installing on the same hard drive? if so, then we must re-test this test with the system on hard drive separate. more if they are on the same hard drive as windows. because there is only one head of reading writing in a hard disk. so this executes to each thing in its time … hoping that you understood.
vmware. in my set ( w7 ) is 20% better in disk read and write ( inside the virtualized ubuntu 14, i use the 14 because yes, no question plz ). then, and is not related, years ago, i cannot use windows 95 ( i like old games without trouble with dosbox and similar software ) with virtualbox, and i dont know why was really slow.
I don't think this is an accurate test. As another viewer puts it, the host OS decides who wins. Furthermore, running two hypervisors simultaneously can't be good; I would imagine one would get the real chipset virtualization capabilities and the other wouldn't.
Did you load exactly the same VMs, i.e the software on both identical etc.? Interesting, the VirtualBox VM seems a lot faster. But I was wondering about your test. Did you run them one at a time and measure the time it took to start up, for instance? Also, can you import/export the VMs between VB and VMW? If you can, it would be interesting to test the same VM…
