For someone looking to start virtualization, would you suggest VMWare instead?
- I use VMWare for my Windows XP/7 VMs, due to the superior support for Dx, Aero, (and oddly enough, Audio) etc - ie. Primarily for Video & other applications.
- I use VirtualBox for my *nix VMs for the superior OGL Support & relatively lighter weight client. - ie. Primarily for various types of servers & the occasional desktop.
As much of the virtualization process is handled by the CPU extensions, as opposed to the respective software's binary translator/recompiler.
Aside from that, the only thing that will make much difference in speed for a VM (again, we're talking typical use cases) is I/O.
Back in the day, VirtualBox suffered worse disk performance as compared to VMWare, but that hasn't been an issue for some time now.
Specifically since the inclusion of SATA/SCSI/SAS multi-threaded, asynchronous I/O support (unavailable for the traditional IDE device).
