It would be an interesting academic exercise to create a setup on Linux that did the same thing but using the extant build tools, and then to do a deep dive into how much of the computer was actually compiling code and how much of it was running the machinery of the OS/IDE/Linkages. A LONG time ago we used to do that at Sun to profile the "efficiency" of a machine in order to maximize the work it did for the user per unit time, vs other things. That sort of activity however became less of a priority as the CPUs literally became 1000x faster.
