Has anyone done any performance profiling for Xen on different
platforms?  I'm wondering if the big (50%+) memory latency advantage
the Opteron's have over the Xeon's makes a big difference in the
context of a Xen host with multiple active guest domains.

Particularly at the moment I'm considering the 2-way situation with
the SunFire v20z vs the Intel SR1400JR2.
