Ok, because of a bunch of projects I'm working on I've access to dedicated Servers on a 3 hosting providers.
As an experiment and for educational purposes I decided to see if I could benchmark how good the IO is with each.
Bit of research lead me to Bonnie++
So I installed it on the server and ran this simple command
/usr/sbin/bonnie -d /tmp/foo
The 3 machines in different hosting providers are all dedicated machines, one is a VPS, other two are on some cloud platform e.g. VMWare / Xen using some kind of clustered SAN for storage
This might be a naive thing to do but here are the results I found.

Ok, so first off what is the best way to read the figures and are there any issues with really comparing these numbers?
Is this in any way a true representation of IO Speed?
If not is there any way for me to test that?
Note: these 3 machines are using either Ubuntu or Debian (I presume that doesn't really matter)
