I believe if you "do it right", PHP7 is already crazy fast. The problem is, without a JIT compiler, those random keys in arrays ("will be object or won't be object?" trope) and crazy dynamic programming is killing all those benefits, and that is typical to those huge organically grown PHP code-bases one usually sees.

Gut feeling: Any attempts on JITting see huge benefits just because of this.
