We should try storing the metatiles directly rather than slicing them up. To optimize even further, we could also return and composite metatiles, then store the other slices in a LockingCache in tilestream. Since the surrounding tiles are likely to be requested at the same time as well, this would reduce the total number of db ops, lower the number of rows and since a large image compresses better than four smaller ones, also lower the db size.
