Before you get too carried away with this benchmark, you should
review the previous comments on this thread.
Not that I don't agree, but lets put things in perspective.
1) The database fits entirely in memory, so this is really only
testing CPU, not I/O which should be taken into account IMO
2) The machines were not "equal" The AMD boxes did not have as much ram.
