From an OO design POV phplib has extremely badly designed database
classes. That's why they are that fast. :-)

No, really, PHPLIB was written on and for PHP3. That is an environment
where classes really are nothing more than namespaces, and where
state and code cannot be kept efficiently in memory, like for example
it would be possible in an application server and with truly compiled
code.

OO design techniques strongly favor such an appserver execution
environment, and PHP does not offer such an environment at all,
in fact, it almost offers the antithesis to such an environment.

PHPLIB was written with the particular execution model used in
PHP in mind and tested on sun4m hardware. That's why it performs
adequately, even today. It is not a bit fashionable, though.
