I'm sure there are some individuals who do care. But the design of Rails and similar frameworks is consistent with what the benchmarks show. They have to be dog slow and they are. I want to assume that this is out of choice, not out of incompetence, hence my conclusion that they don't give a shit. I'm astonished (and actually pleased) to meet so much resistence. Most of the time I just get to hear something about how speed doesn't matter.
