These boxes don't look like being designed for a DB server. The first
are very CPU bound, and the third may be a good choice for very large
amounts of streamed data, but not optimal for TP random access.
Hopefully, when publicly visible benchmarks are performed, machines are
used that comply with common engineering knowledge, ignoring those guys
who still believe that sequential performance is the most important
issue on disk subsystems for DBMS.
