Maybe I don't understand your question... I'm working on the europe extract and I count around 3 times the uncompressed osm file or 30 times the compressed one (using osm2pgsql in slim mode) but dispending of your method it may vary very much. Or you mean tiles on disk usage ? > How long would it take to render on a quite powerfull desktop-machine? 3 seconds for zoom 0 3 times the age of the universe at zoom 30 That all dispend on the max zoom you want.
