I don't have any figures on hardware promises by specific providers, 
but, to me, it's the hardware uptime guarantee that is the clearest 
benefit. I think it would be worth going to VPSes even if it means that 
we get lower performance than we currently do. The slow database 
response ATM comes from machine overloading, not fundamental hardware 
capacity, so pretty much any set-up that lets us add new machines easily 
is going to exhibit higher performance, even if it's built from less 
performant servers (virtual or otherwise).
