> 5. I wonder which implementation of Lua they used.

There is a table with the versions they used¹, but they don't mention the implementation – in can be inferred for some: e.g. for Pascal they used the Free Pascal Compiler.

Ouch, they used Lua 5.3

LuaJIT is at least an order of magnitude(10x) faster.

To the point where a lot of popular libraries (like Love2D) use LuaJIT by default. IIRC, Lapis (Lua-based web framework) can be easily configured for it as well.

I'd be interested in seeing how it fared; Lua really is a nice language.

Lapis afaik also uses LuaJIT by default because it's built for openresty which does use LuaJIT
