LuaJIT

+LuaJIT is a Just-In-Time Compiler (JIT) for the +» Lua programming language. +Lua is a powerful, dynamic and light-weight programming language. +It may be embedded or used as a general-purpose, stand-alone language. +

+LuaJIT has been successfully used as a scripting middleware in +games, appliances, network and graphics apps, numerical simulations, +trading platforms and many other specialty applications. It scales from +embedded devices, smartphones, desktops up to server farms. It combines +high flexibility with high performance +and an unmatched low memory footprint. +

+LuaJIT has been in continuous development since 2005. It's widely +considered to be one of the fastest dynamic language +implementations. It has outperformed other dynamic languages on many +cross-language benchmarks since its first release — often by a +substantial margin. +

+For LuaJIT 2.0, the whole VM has been rewritten from the ground up +and relentlessly optimized for performance. It combines a high-speed +interpreter, written in assembler, with a state-of-the-art JIT +compiler. +

+An innovative trace compiler is integrated with advanced, +SSA-based optimizations and highly tuned code generation backends. +A substantial reduction of the overhead associated with dynamic languages +allows it to break into the performance range traditionally reserved for +offline, static language compilers. +
