If you're looking at per-process data, you're not getting the information you need. You need the Time Profiler instrument, pointed at your application. It's easy to set this up from Xcode 4: Press opt-cmd-I, select Time Profiler from the Instrument popup, and click the Profile button. Then exercise your problem.
This is exactly what anyone would do if they downloaded and ran your project, as you're asking others to do. We're busy. It's your problem. You have the tools and abilities to investigate it for yourself. Measure what's going on, and if you still need help, come back and tell the list what you learned. Even if the CPU is spending all its time in system software, we might still be able to show you how to work around it.
