If I've learned nothing else in the past few days, it's that execution speed is a rabbit hole down which many programmers will dive head first and never look up. The fact is that, in the vast majority of products, if the speed is within reason, nobody cares much. There are more important things to spend your time on, like putting something valuable into your customers' hands sooner. (And no, I will not be drawn into a bogus, "but speed is valuable to customers" debate. It's usually not. "Value" means value in the domain.)
