Two operating systems or a virtual machine

[QUOTE="newjerseyrunner, post: 6027218, member: 553315"] The performance of your VM depends very heavily on what the underlying system is doing. I manage a bunch of servers, all of which have two VMs on them and run onto of a Xen operating system. They work lightning fast and there is no reason that a modern VM should run slowly. My guess is that it was your [I]hard drive[/I] that was being bad. When Windows wants to write to the drive, it does a lot of smart stuff to make sure things are written efficiently. When running two OSs at the same time, they may each want to write to different sectors of the same physical disk so if you have a magnetic hard drive (which I'm guessing you had since you said it was a few years ago) it'll cause shoddy performance. If you have an SSD, you should not have this problem. [/QUOTE]
