    The only performance numbers I really have lying around are from when I
    changed over a centos 5 VM to the virtio driver. I just did a simple bonnie
    test with a 2gb file and limited it to use 1gb of ram (on two cpu's). I
    don't have numbers offhand for some other uses.

    Here are the bonnie numbers from Centos 5 before virtio and after (and
    centos 5 is fairly slow anyway, so your results may vary).

    As you can see, the change was quite dramatic.

    Hope that helps at all,
