<?php if ($handle = opendir('./usr')) { while (false !== ($entry = readdir($handle))) { if ($entry != "." && $entry != "..") { echo "$entry\n"; } } closedir($handle); } ?>

Here you find the average performance (time & memory) of each version. A grayed out version indicates it didn't complete successfully (based on exit-code).
