I've worked in large projects where the build of the entire project (c++ of course) took around 75 minutes, and performance was important (real time visualization of volumetric data). It happened to me _very_ rarely to change a global header that would cause a massive rebuild. Most of the time I would rebuild just the current object I was working on, taking anywhere from 10 to 60 seconds. Yet, linking took massively longer (around 4 minutes as I recall).
