This leads to a question about the nature of the problem:
Do we REALLY need to evaluate all of those 4M values?

If the end result will be sampled in only a few places, then there are definitely more efficient ways to go about it on-demand. If the interesting points are those with certain specific properties (local maxima?) then there will likely be a way to simplify there too.
