<?php $m1 = str_repeat("\x80", 32); $m2 = str_repeat("\x80", 33554432); $end1 = $end2 = $start = microtime(true); $hash1 = hash('sha256', $m1); $end1 = microtime(true); $hash2 = hash('sha256', $m2); $end2 = microtime(true); var_dump( number_format($end1 - $start, 5), number_format($end2 - $start, 5) );

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).
