Bug Type: Performance problem
Description: include, require, et al.
I tried both include() and require():
<?php
if(false)
{
require "some_file.php";
}
?>
and
<?php
if(false)
{
include "some_file.php";
}
?>
Both performed poorly, which is why I'm submitting this report.
At the moment, I've changed my code to use only require() without conditions, as
require() is much faster than include().
Including one more file decreases performance by 2x.
Including another file decreases performance by another 2x.
eg: If you have 8 included files, the performance would be decreased by 256x. This is
the performance drop that I'm pointing out here.

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...
