You ignore completely how is invested the time gained by the developer. Sure you can shave seconds over a few tasks, but a new feature or a new software altogether could save hours on others process. That's how the time of the developer is invested. It's to get a process that takes HOURS to a few minutes versus getting a page that takes SECONDS to a few microseconds. Same goes for the hardware resource. Changing to a bigger server cost less than than my time. That way again my time can save more time on useful stuff. There's billions of hours wasted in business and government in long and meaningless tasks. Optimize that first please before micro optimizing your software.
