Such numbers are meaningless unless you specify the environment
(hardware, disk configuration, file system, OS, jvm, db
configuration), and the type
of load on the db.

What exactly are you trying to do? If you want to compare databases to
see which is "best" or "fastest" you first need to define the type of
load that is important to you, AND that the load will actually
measure the capacity of the databases, and not the network or the disk
or something else entirely.
