I’m just thinking about how much CO2 emission was spared by optimizing performance instead of scaling horizontally.

It would be nice to see the effect on the environment as part of the decision-making process for deciding whether to optimize versus scale.

I think developers have an innate desire to fix performance issues as optimization produces a better understanding of the code and the problem and developers would like to solve the problem in the best possible way. And it helps to know that the problem won’t bite again later.
