with the lazy programmers.
Are you a programmer ... probably not because if you were you would understand that the people who are upset the most about not being able to take advantage of an opportunity to optimize are the very programmers you are disparaging. Like Iconyu posted, it takes time ... and we don't get much say in development cycle timing for a project, typically we are given milestone dates and have to meet them. Recoding something that already works is usually last on the list of things to do unless there is a human perceptable different ... so if it takes 1 second, I'm not spending time the boss is not paying me for to get it to happen in 1 ms given that it will only be evident in a synthetic benchmark that has no bearing on the real world.
