    Again, this is what I just have laying around with no tuning.  Again
    switching from the terrible KVM e1000 driver to the KVM virtio driver with
    FreeBSD as the guest.

       - Network Test
          - Test used: simple scp from machine on same rack
             - Old (e1000) = ubuntu-12.04.1-server-amd64.iso        100%
             657MB   6.4MB/s   01:42
             - New (virtio) = ubuntu-12.04.1-server-amd64.iso        100%
             657MB  34.6MB/s   00:19

    I'm willing to bet someone has more extensive testing than me.  This was
    just a stupid simple test I did to see if the change made a difference.
     For my general use in testing Riak I found that network/fs is way way
    faster on illumos KVM than AWS even when untuned.  Also it is not so much
    slower than the global zone that it affects general performance.  If I was
    making a cluster dedicated to just writing files fast, then I'd personally
    go with OmniOS or SmartOS directly, but if you have other linux needs
    anyway, it is reasonable in my view.  Theo or Eric might have more
    insightful answer since their job is run stuff like this in production.

    FWIW, I used to run all this stuff on virtualbox and had so so so many
    problems I couldn't take it anymore.
