Turbo is a framework built for LuaJIT 2 to simplify the task of building fast and scalable network applications. It uses a event-driven, non-blocking, no thread design to deliver excellent performance and minimal footprint to high-load applications while also providing excellent support for embedded uses.
If someone did write one it would end up high :). The only thing that beats turbo is a custom C server tbh. But that would be a multitude of undertaking to implement a simple server with coherent request handling.
