> I've often wondered how much energy is wasted due to inefficient code and how much that is a problem as planetary compute scales up. I personally believe the majority is wasted. Any code that runs in an interpreted language, JIT/AOT or not, is at a significant disadvantage. On performance measurements it's as bad as 2x to 60x worse than the performance of the equivalent optimized compiled code. > it feels like a moral imperative to make my code as efficient as possible Although we're still talking about fractions of a Watt of power here. > especially when a job will take months to run on hundreds of CPU. To the extent that I would say _only_ in these cases are the optimizations even worth considering.
