Run HHVM as a server
If you spin up HHVM as a fastcgi server and issue requests to it by doing HTTP GETS for the files in /in/ you would see huge perf wins hopefully. It'll save all the command line warmup.
Your server will probably grow unbounded in memory and have to be killed but as long as you have a good restarter it should work. This is how we do unit testing and it sped us up from 10 mins to 1 min.
