Dear all, I used to ask one question about NSCache. Actually, I need to build a view like the 'Photos' application. Now it works, but need to be improved: the speed of dragging, loading images is not good enough. Please give me some general ideas on how to load images on time and manage the cached memory.

Re: Thumbnail view like iPhone Photos app
Well give us something to go on at least! What did you use to build it? What have tried so far in profiling/improving the performance?
