I guess I'm still used to the Old Days of computing, when the speed of 
the CPU was the primary bottleneck. Of course, these days the memory 
subsystem is the primary bottleneck - to the point where algorithms 
which are "less efficient" on paper can actually run faster in reality 
if they have superior cache behaviour.

Obviously, cache behaviour is something I have absolutely no control 
over, so there's no point worrying about it.
