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.
