What is the problem you are seeing? Are the delegates too complex? In theory playing with cacheBuffer you could make everything be loaded at once (same behavior as using a Repeater inside a Flickable instead of a List View) but for large number of items that means too much memory usage. WRT to GridView itself, I'm not sure whether it allocates new delegates when you scroll or whether it reuses the old old ones with new data, as in a circular list, which would be faster (mallocs / constructors are slow). -- Eduardo M.
