Are you willing to increase memory for reduced time? Are you willing to increase time for efficent handling of large data sets? Are you willing to increase contention for CPU cores?

This forces one to imagine what you care about and what you don't care about. Odds are excellent that all the posted answers are both correct and incorrect depending on one's point of view.
