The OP would have done well to try commenting out the entire body of foreach to see if something in the body was slow, or whether it was just the process of iterating through the directories and files. ------------------------------------------------------------------------ [2010-03-10 14:36:58] h dot reindl at thelounge dot net Description: ------------ On Linux it is really easy to read recursive folder-listings with SPL even if there are many files and folders, i need here between 1 and 3 seconds after cold start of the machine on my fedora-box On Windows the same needs between 180 and 240 seconds and "process explorer" shows > 1 MB I/O the whole time, same script, same folders contents, same php-version WHAT do you do on windows? Are you reading all the 30.000 files instead listing them only? Test script: --------------- <?php $files = array(); $folders = array(); $spl_objects = new RecursiveIteratorIterator(new RecursiveDirectoryIterator($path), RecursiveIteratorIterator::CHILD_FIRST); try { foreach($spl_objects as $filename=>$spl_object) { if(DIRECTORY_SEPARATOR === "\\") { $filename = str_replace(DIRECTORY_SEPARATOR, '/', $filename); } if(substr($filename, 0, 2) === './') { $filename = substr($filename, 2); } switch($spl_object->isDir()) { case false: $files[$filename] = $spl_object->getMTime(); break; case true: $folders[] = $filename; break; } } } catch(UnexpectedValueException $e) { error_log('Directory "' . $path . '" contained a directory we can not recurse into'); return false; } sort($folders); ksort($files); $enumerate_list = array('files'=>$files, 'folders'=>$folders); unset($folders); unset($files); ?> Expected result: ---------------- a normal performance Actual result: -------------- waiting minutes to get hughe folder-listings ------------------------------------------------------------------------ -- Edit this bug report at https://bugs.php.net/bug.php?id=51262&edit=1
