#28866 [NEW]: array of objs filling slowness

From: dmirand at abelia-decors dot com Operating system: Linux 2.4 / glibc 2.3 PHP version: 5.0.0RC3 PHP Bug Type: Performance problem Bug description: array of objs filling slowness Description: ------------ When running a portion of script which fills an array with objects, it is easy to notice a significant slowness depending on what has already run before in the script., even if that "pre-processing" is totally independant . The more load that runs before, the slower the filling will be... Under 4.3.6 almost no differences between : - a "just filling" script - a big load followed by a "filling" part Both 4.3.6 and 5.0.0 RC3 compiled from source. Reproduce code: --------------- $big_load = new BigLoad ; $big_load->go() ; unset( $big_load ) ; /* Filling start */ $arr_obj_orders = array() ; foreach( $arr_no_order as $no_order ) { $obj_order = new Order ; $obj_order->load( $no_order ) ; // to show filling avancement echo $no_order ; $arr_obj_orders[$no_order] = $obj_order ; } /* Filling end */ Expected result: ---------------- The expected behavior is of course no slowness with the "filling" part of the script, ie the same behavior as if there was no big load before the filling part. -- Edit bug report at http://bugs.php.net/?id=28866&edit=1 -- Try a CVS snapshot (php4): http://bugs.php.net/fix.php?id=28866&r=trysnapshot4 Try a CVS snapshot (php5): http://bugs.php.net/fix.php?id=28866&r=trysnapshot5 Fixed in CVS: http://bugs.php.net/fix.php?id=28866&r=fixedcvs Fixed in release: http://bugs.php.net/fix.php?id=28866&r=alreadyfixed Need backtrace: http://bugs.php.net/fix.php?id=28866&r=needtrace Need Reproduce Script: http://bugs.php.net/fix.php?id=28866&r=needscript Try newer version: http://bugs.php.net/fix.php?id=28866&r=oldversion Not developer issue: http://bugs.php.net/fix.php?id=28866&r=support Expected behavior: http://bugs.php.net/fix.php?id=28866&r=notwrong Not enough info: http://bugs.php.net/fix.php?id=28866&r=notenoughinfo Submitted twice: http://bugs.php.net/fix.php?id=28866&r=submittedtwice register_globals: http://bugs.php.net/fix.php?id=28866&r=globals PHP 3 support discontinued: http://bugs.php.net/fix.php?id=28866&r=php3 Daylight Savings: http://bugs.php.net/fix.php?id=28866&r=dst IIS Stability: http://bugs.php.net/fix.php?id=28866&r=isapi Install GNU Sed: http://bugs.php.net/fix.php?id=28866&r=gnused Floating point limitations: http://bugs.php.net/fix.php?id=28866&r=float
