This project is dead already. Lua is 4x faster out of the box compared to Python (without LuaJIT!). Lua got fast by having ints and floats at the local side of values, not as a reference. That's in, the int and float value is in the variable itself, not as a reference with a pointer indirection. In Python, every time you do a=a+1 new memory allocation is made for the a+1 object. Java has the same performance issue with boxed types (new Integer), and this is why C# is faster in many benchmarks. (C# cheated with the hindsight advantage of knowing which were Java mistakes)
