<div style="">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.</div>

Thanks for sharing, it is fun to see what people are getting on
their different setups. <br>
<br>
Hopefully more people will post some performance numbers they are
getting with KVM+Linux guest. <br>
<br>
Have a great day!!<br>
