Yes. Everything you add slows P6 down. P6 (clean) starts (boots) in 10 seconds. That can stretch out to 10 minutes if you carry too much content. Ideally, all new content should go to new Runtime(s) created by you. Linked and stored out of P6. Small Runtimes are better. Get some good personal advice from someone you know here on how to structure it. There are many tuts, also.
