That's a serious virtual machine! How big's the physical hard disk it's on?

That seems about the right sort of speeds and times to me. It does require a bit of patience, as you say. It's still incredibly convenient and flexible, though!

I have a 12GB White Box + Oracle 10g Virtual Machine with Fedora Core 3 as the host O/S. If I right-click that folder in nautilus and select 'create archive' (ie, using File Roller with all default settings), I end up with a 2.9GB tar archive, and it takes slightly over an hour to produce it (3GHz PIV). I'm sure I could get better compression with tweaked command line tools, but that's enough to get it onto a single DVD, so I tend not to bother.
