HHVM Beats Stable Version of PHP 7.0 In Recent Benchmark (kinsta.com)
campuscodi writes: PHP7 and HHVM have been exchanging punches for a while via benchmarks. While the PHP supporters were always saying, just wait until the stable version comes out, well... the stable version is out, and a recent benchmark reveals that "HHVM beats PHP7.0 hands down." Compared on: WordPress, Magento, Drupal8, Laravel, PyroCMS, and October CMS. You can still be a "PHP supporter" and favor HHVM, which "serves as an execution engine for the PHP and Hack programming languages."
In our company we have developed HTTP/REST based microservice architecture framework written in PHP, and our performance tests show that PHP 7 is much faster than HHVM:
PHP 5.6.13 - performance about 400 requests/second
HHVM 3.10 - performance about 600 requests/second
PHP 7.0.0 - performance about 750 requests/second
In addition with PHP 7 we avoid many compatibility issues with 3rd party extensions not or badly supported on HHVM. Consequently HHVM is going to be obsolete after PHP 7 stabilises a bit.
(I have also deployed PHP 7 on some Magento eshops and the performance gain is terrific compared to PHP 5.6.)
