The Green Side of the Lua
The paper titled 'The Green Side of the Lua' examines the energy efficiency of the Lua programming language compared to other languages. It highlights the significant performance improvements achieved through just-in-time (JIT) compilation. The study finds that LuaJIT can be substantially more energy-efficient than standard Lua interpreters, approaching the efficiency of C.
- ▪The United Nations' 2030 Agenda emphasizes the need for energy-efficient software to reduce carbon footprints.
- ▪Lua is less energy-efficient than compiled languages like C, despite its popularity.
- ▪LuaJIT compilers significantly outperform standard Lua interpreters in both execution time and energy consumption.
