    Hi Dave,

    Do you find php7 faster than HHVM?

      It depends on the type of load on the server. In almost all cases, HHVM is still faster – it is compiled after all, versus interpreted PHP 7. I normally set up HHVM as the primary engine with fallback to PHP 7 in case of incompatibilities (server 500 errors).

      If a client’s server doesn’t have much RAM, then I just use PHP 7 for them as the performance problems caused by reduced memory (because running two engines) is a bigger impact. I’m expecting further performance improvements from both HHVM and PHP 7 in the future. PHP 7 is definitely FAR better than PHP 5.6.
