"And I keep reading Xen is faster than KVM, but I haven't tested that in my environment yet."

From what I've seen, Xen is faster than KVM about half the time, and vice versa the other half.

And it's hard to predict which will be faster for a particular workload.

I know Phoronix might not be all that populair with the development community, but their results showed something like that too.

Judging by some of the other things I've seen online, KVM has gotten better and Xen and KVM seem to be getting closer in performance and I think I've even seen them supporting paravirtualisation APIs from each other.
