centos luajit installation instructions – In the following tutorial I will show you how to install and use the LuaJIT Compiler on your CentOS box.

Before you continue you should already know what is Lua and JIT Compiler.

 

What is LuaJIT?

LuaJIT is a Just-In-Time Compiler (JIT) for the Lua programming 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.
