It's a natural assumption, but consider what happens as projects get larger:
- compile time is roughly linear in the number of lines of source code
- link time (because of having to resolve everything against everything else)
So when things start scaling up, link time can easily overhaul compile time.
And that's before you even factor in that use of make and dependency testing
.c files against .o files means that you don't often have to recompile many
files of a project most times you build it, whereas the final link always has
to link the same number of .o/.a files together.
Can't think of a witty .sigline today....
