The system is ZFS-only and equipped with a single WDC disk. I'm also running VBox 4.2.6 with Fedora Linux (64 bit) as guest; the virtual machine has 1.5GB RAM allocated. There was and is no delay in using the virtual machine. Even under heavy load (load level > 20) the system is interactive, that is, I can watch videos, surf the net, etc. without almost no hiccup. Only if memory is really scarce and I'm copying a large file (~7.5GB) the system becomes kind of slow, e.g. it takes some time to switch between different applications. Up to now, I didn't need to kill my machine to get it working again. HTH, Philipp
