Performance counters on the iPhone

Question

I'm trying to find the best method of incode performance monitoring on the iPhone.

On a windows platform I would use the following functions :

QueryPerformanceCounter((LARGE_INTEGER *)&ctr);
QueryPerformanceFrequency((LARGE_INTEGER *)&freq);

Does anything like this exist on the iPhone? Whats the highest resolution I can time something without using an external tool such as Instruments or Shark?

I think mach_absolute_time is what you are looking for. For more information:
