Yeah, but even avoiding levels 0-3, the estimated size is several times larger than the actual size. Faster db access would really help too (along with Winmapper). Maybe v3 will have to do a "compromise" between the single DB (which seems superslow, especially as it gets bigger) and the single-tile files of 1.0. How about files with a max of 256 tiles? (16x16 "supertiles")

hehe, I know, not this year.
