<?php $index = "stuff string"; $data = 'foo'; $cache_id = 'bar'; $tmparr = new stdClass; $tmparr->name = $cache_id; $tmparr->size = strlen($data); $index[] = $tmparr; var_dump($index);

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).
