I specifically said that I was talking about an engineering tradeoff, however - that is, when you have to choose between one or the other. Excluded from that is the possibility of improving both memory and CPU consumption at the same time - that means that you haven't hit the edge of the curve, so to speak.

I just wanted to correct that by saying that its utilization is very expensive for the CPU. Rather the trade off you're thinking of is "caching vs. realtime computation" rather than just "memory vs. cpu". Outside caching, it's pretty universal that more memory utilization just means poorer performance, both in wallclock time and in CPU utilization.
