That's a good question. PHP 5.5 with the newly-open sourced (and integrated) opcache gave it a good run for its money before this optimisation sprint [1]. Under real-world 'bloated framework' usage, HHVM was already pretty cool [2]. I'd like to see the results after this speedup. 1. For simple code only - once it's more computationally intensive, HHVM wins. http://www.alexfu.it/2013/10/22/symfony-benchmark-on-hhvm.html http://www.alexfu.it/2013/10/22/symfony-benchmark-on-hhvm.ht... 2. http://blog.liip.ch/archive/2013/10/29/hhvm-and-symfony2.html http://blog.liip.ch/archive/2013/10/29/hhvm-and-symfony2.htm...
