I've an already developed social website like Facebook. This website has been developed using PHPFox v3.0.7 (which is a social networking platform created in PHP).
The website functions are working well, no issues with it. The main, major and serious issue I'm facing with the website is the slow execution speed. For operation it takes too much time and user has to wait for a longer time. This really irritates the user and affecting the performance of a website.
So, I did research on if Facebook can execute at rapid speed in spite of heavy user load and continuous operations why can't my site?
Then I come to know HipHop Virtual Machine (HHVM) which they have developed and implemented in Facebook.
So my question is can I use the same approach of using HipHop Virtual Machine (HHVM) into my social website to increase the website execution speed? If yes, how, where to start, what's the best possible and standard way of doing it? If no then why?
