You may want to use toggles to swap between Auto/AOE instead of using Dual mode. I don't see anything especially egregious in terms of time spent generating recommendations, and I'm not aware of anything that would cause excessive rechecking of recommendations.

In the same way that 4 icons costs more CPU than 2 icons, 2 displays with multiple recommendations costs more CPU time than 1. I'll continue to explore optimization opportunities in the addon, but at the moment, this looks like the cost of doing business, as we discussed.
