May I also chime in? If I wanted my machine to run at Celeron speed, I would not have bought a core i5. I think it makes no sense to select the "powersave" governors by default without telling the user in any way. Any non-expert user will not know why his machine runs 2x more slowly on Linux than Windows. It sounds like a very good reason to drop Linux (or, maybe, try a different distribution).
I have read somewhere that intel-pstate's new "performance" is nicely engineered to cover most use cases; unlike the old "performance" it doesn't mean the machine will always consume as much power as possible. In fact the new "performance" consumes less power than the old "ondemand". The latter disappeared because the new "performance" covers the same use cases and more.
