iPhone App Running Slower on Simulator

I am currently working on an iPhone app where I use 2 main timers that make the game work as one piece. The only problem I've encountered so far is that when I run it on the iOS Simulator from Xcode the game seems to lag a bit, and all of the animations run sl开发者_如何学运维ower. I'm not sure if this is a memory issue, but isn't the iOS Simulator supposed to run just as smooth as the iPhone? When I run it on my iPod Touch 4th Generation, I don't encounter this problem. Is there a way I can fix this, or does anyone know why this happens?

The frameworks are designed to work with specific hardware on device for graphics acceleration. This is not present in the simulator, so you'll see diminished performance on graphics-intensive applications. You might however see increased performance in the simulator in non-graphics related areas. The bottom line is always test on real hardware - the simulator is just a convenience.
