I am not using any PHP bytecode cache. About one year ago I tried eAccelerator which causes Apache freeze. Now I installed ZendOptimizer and load increased!! by 50% :o( -- Miroslav Lachman The upgrade from 5.1x to 5.2x make same change into memory utilizzation (ex. Zend memory manager) and apache2 SAPI. (try to check the apache memory utilizzation) You can check the php-5.2.0 changelog to find out some important change for yours applications (no fixed bug) or retry with new version of php.
