Processwire with HHVM

[gurkendoktor]

As I already said in this thread, I have Processwire running with PHP7 and also HHVM. 

HHVM is an open-source virtual machine designed for executing programs written in Hack and PHP. HHVM uses a just-in-time (JIT) compilation approach to achieve superior performance while maintaining the development flexibility that PHP provides.

So this thread is dedicated to all the question and experiences people run into when trying to get ProcessWire work with HHVM. I will start with a small tutorial, so you can try it yourself and make your own mistakes instead of repeating mine

I highly recommend running HHVM on a production system only if you know what you're doing.

For a general comparison of the performance of both PHP7 and HHVM, I suggest this site. In general, you should have plenty of memory to run HHVM. 

Here is a tutorial how to install HHVM.
