I'm not sure if performance has to be first. One could for example do proof of concept style of work with some higher level language before starting to create the actual product which then should also take the performance aspects under consideration. I think we actually waste a lot of energy by not encouraging our selves to pay attention on the performance. Nature sort of demands efficiency in long run. Yes?
