- The UN's 2030 Agenda emphasizes energy-efficient software to cut carbon footprints, where programming languages impact consumption.
- Lua is popular but less energy-efficient than compiled languages like C, prompting a study on its performance.
- This empirical analysis covers 25 Lua interpreter versions and JIT compilers, measuring execution time and energy use.
- LuaJIT compilers vastly outperform standard interpreters, using about 7x less energy and running 7x faster.
- LuaJIT nears C's efficiency, requiring roughly 6x more energy and running about 8x slower.
- JIT compilation significantly boosts both performance and energy efficiency in interpreted languages like Lua.
