<?php $a = new stdClass(); $a->id = "2"; $a->name = "hek"; $b = new stdClass(); $b->name = "hek"; $b->id = "2"; echo serialize($a) . PHP_EOL; echo serialize($b) . PHP_EOL;

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).
