Superefficient → It is formed from "super-" (meaning above or beyond) and "efficient" (from Latin "efficere", meaning to accomplish or bring about). The word "superefficient" means to accomplish tasks in a manner that is above or beyond normal efficiency.
Think of being "above" ('super-') normal levels of "accomplishing tasks" ('efficient') — that's why superefficient means extremely efficient.
