You seem to be looking at the wrong source code. The "Energy Efficiency across Programming Languages, SLE’17"authors provided this repo — https://github.com/greensoftwarelab/Energy-Languages/blob/ma... https://github.com/greensoftwarelab/Energy-Languages/tree/ma... For a single outlier (regex-redux) there's a 12x difference between the measured times of the selected C and C++ programs. Even so, that mostly messes up the results because the arithmetic mean is used rather than the median. https://benchmarksgame-team.pages.debian.net/benchmarksgame/...
