At the risk of distracting from the central topic, I'd like to point out tha=
t HHVM's times are almost certainly based on non-JITted code.  The JIT doesn=
't kick in until the 11th request, and 3v4l scripts are, by definition, only=
 run once.

PHP is optimized for blind interp, so it's doing better in that mode.
