I like your use of the word "might" :-) It's also not hard either to make things slower that way. Some of the tuning trade-off from Linux on x86 does not apply here (eg any use of CPU to speed up disk I/O is justified because it would be wasted otherwise). When you have enough virtual machines competing for resources and you put some effort in allocating the resources, the load may very well spread already over the ranks. The desire to configure an individual server to monopolize the subsystem may make more sense in a discrete server environment.
