Are you experiencing some specific performance problem? Or are you
just worrying before you actually have a reason to? :) Honestly, I
don't think it will cause any problems.
This was recently discussed in another thread, but you should make use
of __autoload():
<http://www.php.net/autoload>
Besides the fact that it will only load classes as necessary, it will
also save you from having all those require()'s at the top of your
page.
