I’m surprised their benchmark only saw a 200% performance improvement. LuaJIT is way faster than Lua in many cases.

So the PHP implementation was built into the opcache extension which already gives a massive speed up over purely interpreted PHP.

If you benchmark JIT PHP vs PHP with no opcache you will see 500% speed up or more depending on the workload.

Of course most PHP web servers tend to be pretty IO bound. The project I work on sees ~a 20% in best case response time which is quite nice.
