The luaot compiler is a simplistic compiler that compiles Lua bytecode to C. One may see it as a partial evaluation of the reference Lua interpreter. The main optimizations are that Lua jumps are converted into C gotos, and that there is no overhead of interpreting bytecodes at run time. Additionally, the C compiler will be able to optimize some kinds of things, specially constant folding and dead-code elimination for the opcodes that include immediate parameters.

-The performance gains depend on the kind of program being run. For numerical benchmarks it can be twice as fast as regular Lua. But overall, it isn't super impressive, and is not as fast as LuaJIT or Pallene.
