If your tiles use the OpenStreetMap / Google style 900913 projection
then you could consider using mod_tile[1]. This renders and stores each
block of 8 x 8 PNG map tiles inside a single file on the disk. This
makes the storage and access much more efficient. It cuts down the
number of files on the disk by 64 and allows nearby tiles to be read
from a single file.
