ABSTRACT
Consider a large document with a lot of images in it. Images are expensive objects in terms of memory size and thus time to load and decode. This means the document will be slow to load as it takes a long time to read from disk. The result is that the user will perceive the word processor as slow and perhaps buy another product. So, the challenge is to make the system load the document fast even if it contains a large number of objects that are slow to load.
