Interestingly enough, I was talking to Quora engineers about the problems they were facing scaling their website, and there was no doubt about it: CPU was one of the big problems. Yes, yes, I know, don't overengineer your systems in the beginning, but I really get the sense that if software needs to scale, it is going to need to scale in all dimensions, including CPU. I'll note that the "JVM has had more hours poured into it" argument is meant to give PyPy the benefit of the doubt!
