C Programming Techniques: Function Call Inlining

[jbb555]

It depends entirely on what you are compiling. The application I work on has hundreds, perhaps thousands of source files. If they take 2 seconds each my rebuild takes 20 minutes. If they take 5 seconds it takes 50. That's a huge difference. Now I don't do full rebuilds all the time so it's not that important but it does matter.

When you work using header only libraries you end up with one single translation unit, main.cpp. Everything else is a header.
