I actually picked up this deal too, here's my report: http://serverbear.com/benchmark/2012/08/12/TjvnpPGESa3sOUHm

Just make sure you're using the Virtio drivers, I think it gets set to IDE automatically. Not sure how @John feels about making Virtio default.

I've mention it in the top of the post, but you can visit it here :

john · August 2012

@serverbear, we have clients that use operating systems that do not support virtio by default. The default settings are to ensure maximum compatibility. I have added information to the initial setup email that clients should switch to virtio to get the best performance. I have also been manually checking VPSs a day or so after they are setup and sending a email to the client informing them about virtio.

@Jack http://www.lowendtalk.com/discussion/comment/107506
PM me and we can discuss a custom plan.

Randy · August 2012

I Cant wait to see the results of mine:)
