LuaJIT

+LuaJIT is a Just-In-Time Compiler for the Lua^* +programming language. +

+* Lua is a powerful, dynamic and light-weight programming language +designed for extending applications. Lua is also frequently used as a +general-purpose, stand-alone language. More information about +Lua can be found at: » http://www.lua.org/ +

Compatibility

+LuaJIT implements the full set of language features defined by Lua 5.1. +The virtual machine (VM) is API- and ABI-compatible to the +standard Lua interpreter and can be deployed as a drop-in replacement. +

+LuaJIT offers more performance, at the expense of portability. It +currently runs on all popular operating systems based on x86 CPUs +(Linux, Windows, OSX etc.). It will be ported to x64 CPUs and other +platforms in the future, based on user demand and sponsoring. +

Overview

+LuaJIT has been successfully used as a scripting middleware in +games, 3D modellers, numerical simulations, trading platforms and many +other specialty applications. It combines high flexibility with high +performance and an unmatched low memory footprint: less than +120K for the VM plus less than 80K for the JIT compiler. +

+LuaJIT has been in continuous development since 2005. It's widely +considered to be one of the fastest dynamic language +implementations. It has outperfomed other dynamic languages on many +cross-language benchmarks since its first release — often by a +substantial margin. Only now, in 2009, other dynamic language VMs are +starting to catch up with the performance of LuaJIT 1.x … +

+2009 also marks the first release of the long-awaited 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 a highly tuned code generation backend. This +allows a substantial reduction of the overhead associated with dynamic +language features. It's destined to break into the performance range +traditionally reserved for offline, static language compilers. +
