LuaJIT makes the Lua mandelbrot program run 95 times faster than Ruby's, whereas the stock Lua interpreter is only 17 times faster.

Better yet, LuaJIT is a drop-in replacement. There's no reason not to use it, as far as I know.



Well, LuaJIT only runs on x86, and only in 32-bit mode. Though, the work-in-progress LuaJIT 2 is supposed to be easily portable to ARM or other architectures.


I love the "only 17 times faster" bit ;-)


Try comparing ruby to c++!
