Fixing code that never runs saves nothing.
Developers often optimise the code they suspect, not the code that is actually hot. A 50% gain in a function that takes 2% of the runtime is a 1% gain overall.
GreenCode helps tackle this by building a load test from the system's own endpoints, recording energy as well as speed while it runs, and ranking the hotspots by the energy they use. More on this.
Fixing code that never runs saves nothing. Most of us optimise the code we suspect. Not the code that is actually busy. Say you make one function twice as fast. If it only takes two percent of the run time, you save one percent. All that work, and the meter barely moves. And every change adds a little risk. Here is the fix you can use today. First, profile the real workload. GreenCode's Constitution skill tells AI coding agents to do this first. Find where the time and the energy actually go. Then only work on the parts that take more than about five percent. Leave test code, prototypes and rarely used code alone. Measure each change with the Constitution's profiler or green-languages, and keep what saves. GreenCode helps tackle this by building a load test from your system's own endpoints. It records energy as well as speed, and ranks the hotspots by energy. That was GreenCode Tech Tip number fifty-four. Follow for the next tip, and find more on greencode.ai/tech-tips.
