From:             [EMAIL PROTECTED]
Operating system: Windows 2000
PHP version:      4.0.4pl1
PHP Bug Type:     Performance problem
Bug description:  include, require, et al.

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...
