From: mauroi at digbang dot com Operating system: Win32 PHP version: 5.2.2RC1 PHP Bug Type: Performance problem Bug description: relative paths affecting script performance
Description: ------------ First of all, I couldn't reproduce this on Linux. Maybe because it doesn't exist, or maybe because of worse perfomance on filesystem operations on Windows. We've found a performance degradation between PHP5.1.6 and PHP5.2.x (also checked with PHP5.2.2rc1) when including a file with a relative path. It gets notorious if using include_path and it has a big number of directories. In the provided zip file you'll find 8 directories. Only one of them contains the file that will be required by the main script. So, script.php & script1.php show the problem. script.php only requires the file one time, and even in that case you'll see the difference. script1.php iterates including a non-existant file (that's why errors ar supressed) and the execution time is twice as big. At first glance this could look as a bug with less importance, but any framework that uses __autoload & include_path with some sort of frequency, will be slower on PHP5.2 on Windows. Also, any site using MVC (not even using __autoload) and relative paths could be affected. Thank you very much.
