You can use instruments to find out the number of fps. Very useful to optimize uitableviews.

  On a tangent, anyone come up with any reasonable solution to simulating the iPhone's hardware environment from XCode (it so needs a slow-down plugin). It's nice to run stuff on my CoreDuo but painful to see how slow it runs when it's actually on the iPhone.

    No. You need to test on the iPhone. The iPhone is not just a slower version of your Mac. It has totally different performance characteristics. And they have a different feature set even, like other than missing apps on the simulator, certain animations are missing in the simulator.

    The only way to get accurate performance metrics would be to emulate the hardware at the silicon level. On the one hand, this is extremely difficult, on the other hand, it's also very slow. You're pretty much just going to have to suck it up and test on real hardware. Compared to certain game consoles, the iPhone tools are pretty good.
