<?php $str = "a".str_repeat("\xCC\x8A", 100000); var_dump( 1 === preg_match_all('/\X/u', $str), 1 === preg_match_all('/(?>\PM\pM*)/u', $str) );

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).
