Probably someone downvoted your question because they think it doesn't contain enough information about your system and your problem, however it is wrong of them not to provide an explanation. Please read the FAQ which contains guidelines for the use of this forum.

To answer your question, processing that much information (3264x2448 pixels) on an iOS system is bound to be slow. Do not forget you are working with a handheld device that has limited processing power compared to a PC system.

IOS is known to be slow compared to PC in many different reasons. In my case first time I used algorithms on IOS they ran 200 times slower than on PC. I did some work and learned some tricks how to speed up IOS: http://stackoverflow.com/questions/11219240/maximum-speed-from-ios-ipad-iphone And of course you always can try to work with smaller image. Handheld, battery powered ARM is not PC-like monster.
