<?php $pass = str_repeat('a', 1024 * 512); echo strlen($pass . $pass), "\n"; echo smemory_get_peak_usage(), "\n", memory_get_peak_usage()/(1024*1024) . 'MB';

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).
