It's true that it's not always faster to compile each module

I already knew that. It seems to me, however, that when that's

the case, the practical difference is negligible. Even if 10x
slower,
the linker will take longer anyway. Because it'll all still be
under a
second. That's been my experience anyway. i.e. It's either
faster or it
doesn't make much of a difference.
I just tried compiling one of my project. It has a makefile
that does separate compilation and a shell script I use for
unit testing which compiles everything in one go. The makefile
takes 5.3 seconds, does not including linking since it builds a
library. The shell script takes 1.3 seconds which include
compiling unit tests and linking as well.
change one file and see which one is faster with an incremental
build.
