Complete agreement with the last sentence. I can think of two projects in my past five years that really showed performance sensitivity. I knew that at design time so I chose to care about where data sat in memory and how it would behave in multilevel caches. All other projects, couldn't care less where the kitchen dude stored my pots, and he never lost one. None of those projects jumped from performance agnostic to performance sensitive overnight.
