The main benefit of caching is that the tiles are ready to go.
Decompressing and recompressing images on the other hand is very
expensive. For two layers you typically need to decompress 9x2 = 18
tiles (3 x 3 screen, 2 layers) and then recompress 9 composited tiles.
Instead, create a layer group in GeoServer (consisting of X and y) and
use that in the client.
