There's a popular line of thought that says don't waste time on optimization because developing features is more important than saving money. True, you can always add resources, but at some point, especially in a more mature part of a product lifecycle: performance equals $$$.
Two great examples of this evolution come from Facebook and Google. The upshot is that when you spend time and money on optimizing your tool chain you can get huge wins in performance, control, and costs. Certainly, don’t bother if you are just starting, but at some point you may want to switch to big development efforts in improving efficiency.
