<?php function rec($dir, $depth) { $d = dir($dir); if (!$d) return; while ($entry = $d->read()) { if ($entry == '.' || $entry == '..') continue; echo $depth . $entry . "\n"; if (is_dir($dir . '/' . $entry)) { //rec($dir . '/' . $entry, $depth . " "); } } } rec('/opt', '');

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).
