You say that you use conditional statements to determine whether or not to REQUIRE a
file.
Just to make sure: You're not using require or require_once inside a conditional
block, such as:
<?php
if($condition)
{
require "some_file.php";
}
?>
I'm asking this, because require and require_once are UNCONDITIONALY called, see the
manual pages for require and include on this topic.

I discovered that the include(), require() or include_only(), require_only() functions
have a profound effect on performance. I use conditional statements to conditionally
require files, however, it seems that the PHP interpreter has a performance problem
with this.
Commenting out all the require() or include() code shows that performance improved by
200%.
Web Stressing the app and PHP, I have found that PHP can sometimes crash with an
Access Violation at 12345 and CPU usage maxing at 100%.
Memory leaks very much when CPU usage is at maximum threshold.
Zend Optimizer seems to reduce performance by a noticeable amount. It does not seem to
reduce CPU usage, unfortunately.
I got the best performance from PHP using page cacheing. Results seem to show that
it's faster than static HTML...
