<?php $f = function() {}; var_dump($f()); // 'null' var_dump(function() {}); // 'object(Closure)[1]'

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.
