The Green Side of the Lua | Hacker News

Hacker News users debated a benchmark paper/table comparing energy, time, and memory across languages.

Critics said the results mostly reflect runtime implementations and benchmark-game code quality, not the languages themselves.

Commenters noted that fair comparisons need to account for engines like LuaJIT and V8, not just Lua or JavaScript on their own.

The thread underscored how language benchmarks can be misleading when they reward tuning, libraries, and runtime differences.
