If I pool all unused objects such that no object needs to be GC'ed, does it still perform scanning? What are other good ways to avoid its overhead? As you might tell, I know rather little how D's garbage collection works. I'm working on a game engine and trying to be as resource efficient as possible.
A GC collection will run when you allocate with 'new' and there is not enough memory already reserved by the gc. So if you don't use 'new' then it won't run a collection, otherwise it might. You can disable all collections by importing 'core.memory' and calling 'GC.disable()'.
