#15876 [Opn->Fbk]: odd slowdown in calling small sections of php code

ID: 15876 Updated by: iliaa@php.net Reported By: ddp@deakin.edu.au -Status: Open +Status: Feedback Bug Type: Performance problem Operating System: linux 2.4.17 & solaris 8 PHP Version: 4.1.1 New Comment: Please try using this CVS snapshot: http://snaps.php.net/php4-latest.tar.gz For Windows: http://snaps.php.net/win32/php4-win32-latest.zip Previous Comments: ------------------------------------------------------------------------ [2002-03-05 22:28:39] ddp@deakin.edu.au Forgot to add the timer code is based on // Deathhead's Timer // http://phpclasses.upperdesign.com/browse.html/package/431/ ------------------------------------------------------------------------ [2002-03-05 09:27:26] ddp@deakin.edu.au here's part of the code that causes the problem: if(isset($timer)) $four=$timer->get(); if( !empty( $ev->repeat_id) ) printf( "&REPEAT_ID=%s", $ev->repeat_id); if(!empty($end_date)) print "&END_DATE=$end_date"; if(isset($timer)) $five=$timer->get(); Produces the following timings: four=3.0422940254211, five=3.4876440763474 Interestingly, this is repeatable many times through several different pages, but in different sections of code (all seemingly innocuous and they definitely 'behave' correctly most of the time, e.g. 1 time out of 15 in a loop on the same page the above code will give that slow response, the other times it will execute quickly): four=4.3863810300827, five=4.3864229917526 Other info (sorry, I don't think I can give you a small script).
