Yeah, good question. I was wondering this myself. I'm not a guru in this area, but I believe the Stormondemand servers are still virtualized (Xen) but you get the entire server / disk to yourself rather than sharing. They do this to make the server more like a VPS to manage.
I'm not sure where the poor IO comes from with VPS. Certainly part of it is from sharing, but I'm sure some of it is from the overhead of virtalization as well. So, does the Stormondemand servers still take a hit on IO as compared to a "normal" dedicated?
I could be wrong and totally talking out of my a here though. Someone please correct me. ;)
