Windows 7, 64-bit, SATA disk and 2x3 GHz is converting Finland.osm.pbf in about
8 minutes for me. But execution time does not increase at all linearly.
Germany.osm.pbf is about 10 times larger in filesize but ogr2ogr had to work
about 8 hours with it, thus roughly 70 times longer. Obviously I would save 6
hours by splitting the German pbf file into 10 smaller ones, running ogr2ogr ten
times and combining results with ogrtileindex for use with Mapserver.
