<?php $obj = 1.00; var_dump($obj); $jsom=json_encode($obj); var_dump($jsom); var_dump(json_decode($jsom));

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).
Note: hhvm uses a JIT which only kicks in after a few runs. Since we run scripts only once, hhvm always runs slower.
