I was just addressing the I/O slowdown thing, where if you double the money you might very well get more than double the performance, and get two VM's running faster than on the cheaper hardware. But it seems he's already doing some virt. Just not enough detail to sort that out. Although it would really be interesting to me to see scheduler settings that would indeed allow something of a 'privileged' ssh or an OOB console that would be responsive even under a punishing load with lots of swapping, which is what the OP originally asked about.
