Android's build system now generates Ninja files, which are semantically very close to non-recursive Makefiles, so it's a real-world example you can examine and measure. Android's build files currently add up to 1.5gb of text(!!!), which even with a fast parser take some time to load (~10-20s). It's discussed further in this thread (in which among other things I suggest that maybe something is going wrong when you have 1.5gb of text): https://groups.google.com/d/topic/ninja-build/htlu9akobq0/discussion https://groups.google.com/d/topic/ninja-build/htlu9akobq0/di...
