-It's no secret that the performance jump of PHP 7 was originally initiated by attempts to implement JIT for PHP. We started these efforts at Zend (mostly by Dmitry) back in 2011 and since that time tried 3 different implementations.  We never moved forward to propose to release any of them, for three main reasons:  They resulted in no substantial performance gains for typical Web apps;  They were complex to develop and maintain;  We still had additional directions we could explore to improve performance without having to use JIT.+It's no secret that the performance jump of PHP 7 was originally initiated by attempts to implement JIT for PHP.
