the processor is used a lot when I zoom in or zoom out, but the projection is normally already adapt, the <cache format> section dont seems to improve (perhaps I dont use it well), I tried to use the gdal_translate to tiled the data but it ddont seems to improve either...
<!--Define a cache that will save tiles to the osgearth_cache directory-->
Also, for imagery, you'll probably be fine keeping the default
tile_size of 256 of changing it to 64.
