Not at all. The final size of a map shouldn't be more than 3 or 4MB, which is not a lot at all. What takes up most of the compile-time is the light generation (how the light bounces off different surfaces and things like that) and that process needs to be done only once.
you mean once per every time you compile with new items in your room? and how do you tell how many GB your room is?
