Haven't seen that.  While it's certainly not comparing apples to apples,
moving from Outlook on Windows to a virtualized Linux IMAP server, searching
20,000 messages went from 150 seconds to 15.

Why is that?  If you want to do incremental backups, you can run the backup
software in the VM just as you would a physical machine.  On the other hand,
backing up the whole VM is incredibly easy, especially in these days of
cheap disk storage.

More importantly, virtualization shields you from hardware failures.  The
way I'm configuring my system, I can lose any piece of my hardware,
including the motherboard on my primary server, and still function.  It may
be a little slower, but I'll function.  I just move my VMWare image onto my
primary workstation and run from there until I replace the server.

Sure, I could do the same with redundant hardware, but I am frugal <grin>.
I prefer to use my machines as much as possible.
