SQL is slower in our environment. We helped with the testing and have the metrics. NOTE: I said OUR environment. Your loads may not equal our loads.
Virtualization has overhead and complexity wether it's VMware or HyperV. The question is depending on your environment and application loads if Virtualization is appropriate to your needs. We have one of those new fangled SANs from Hitachi. It will be a condition of future employment that they not have HItachi SANs there.
