If I understand correctly, what you did is normal lazy loading, once a coverage is loaded, it stays in memory, you're just avoiding up front loading... meaning that during encoding all coverages end up being loaded in memory. ImageIO deferred loading is instead a JAI operation that uses the JAI tile cache, it loads tiles there on a as needed basis, and if there are too many, the cache throws them away and they will be reloaded if needed. So you get good memory control, at the expense of potential more I/O Cheers Andrea == GeoServer Professional Services from the experts! Visit http://goo.gl/it488V for more information. == Ing.
