I have a cached layer with create tiles on demand - allow clients to cache tiles locally set, using 256/256 PNG tiles. When I'm zooming in (mouse scroll wheel) it draws/shows really fast. I get down to the bottom layer and cant zoom any further. sometimes when I zoom back out one with the scroll wheel it takes a really long time to draw/load. almost as if its redrawing even though I viewed it just a few seconds ago. I checked the resources on the server when this happens and it does seem to be drawing. Is there any reason for this? any way I can keep my layers speedy with navigation?
