In my experience, you really only start to see these problems at the tens of thousands of flashcards level. I have ~70,000 mature flashcards and also have the growing backlog problem, even if I don't add new cards for weeks. My collection is 8 years old.

I agree that making good flashcards helps alot. Another big thing is to make sure the knowledge graph is connected, eg there are no 'orphaned' individual cards / groups of cards. Those tend to suffer seriously from decay for me.
