#36166 [Com]: perfomance loss since php version 5.05

ID: 36166 Comment by: kristian dot raue at jedox dot com Reported By: fschaper at intux dot org Status: Feedback Bug Type: Performance problem Operating System: WindowsXP PHP Version: 5.1.2 New Comment: Here is a short 20 line php script that reproduces the bug. http://www.jedox.com/impulse/slow_php5_include.zip There still is the 26000 line of code include file (fx.xcc). But this is what the bug is all about. The bug has nothing to do with large arrays, it is about including large include files. This took 0.5 sec in PHP 4 and PHP 5.05. In PHP 5.1.2 this takes 3 sec. The include file is a simple dummy file, please look at the code, it is trivial, 26000 line of repetious code. Previous Comments: ------------------------------------------------------------------------ [2006-01-26 16:48:29] tony2001@php.net Thank you for this bug report. To properly diagnose the problem, we need a short but complete example script to be able to reproduce this bug ourselves. A proper reproducing script starts with <?php and ends with ?>, is max. 10-20 lines long and does not require any external resources such as databases, etc. If possible, make the script source available online and provide an URL to it here. Try to avoid embedding huge scripts into the report. ------------------------------------------------------------------------ [2006-01-26 16:23:04] fschaper at intux dot org Original test with php5.05 ~ 0.5sec php5.1 ~ 4.5sec ------------------------------------------------------------------------ [2006-01-26 16:21:28] fschaper at intux dot org Description: ------------ Since php version 5.05 we noticed an rather large performance hit in general while working with rather large array's. We have prepared an short sample which illustrates the problem. in php5 the script takes about 0.5 seconds to perform. The latest snapshot release from today and the current release version of php take about 4.5 seconds for the same task.
