I am such a kind of person that i am completely not on-time with marketing, namings, etc.. I just asked what CPUs will support AES-NI which is important for me (geli speedup) and got that in Dell Server ;) Virtualbox works great with windoze on that machine. >> FreeBSD have linux emulation. i think you should use it instead of VBox if >> you need to run linux environments under FreeBSD. > > Yes, it does.

Are you running on 9.x or 8.x? for production - yes (6 instances of windows XP). Virtualbox does never make main workload for me, it is just addon. On FreeBSD 8.3. But i've tried Windows 7 64-bit and it worked fine. didn't see any problems with latency you describe
