That depends on how expensive those calculations are relative to memory access. CPUs are very fast at doing a ton of math but very slow at reading or writing to random memory.

Yes, of course, but my point wasn't that if you cache all results your software will be faster. My point is just that it is possible to write code that consumes more memory, and runs faster under some circumstances, which refutes the ops claim that all software that uses more memory is slower.
