This test may be interesting. I took timings from converting 
finland.osm.pbf and germany.osm.pbf with spatialite_osm_map. 
It is doing roughly same thing as ogr2ogr, that is, reads 
nodes from OSM file and resolves point, line and polygon
features. Enviroment:

Windows 7, 64-bit. 6 GB memory 
64-bit spatialite_osm_map.exe, version numbers:
SQLite version: 3.7.13
SpatiaLite version: 3.1.0-RC2

Command:
spatialite_osm_map -d osm_map_testfi.sqlite -o finland.osm.pbf -jo

Results:
Finland 11 minutes
Germany 10 hours

Memory usage of spatialite_osm_map process was very low, under 50 MB.

Similar behaviour of ogr2ogr and spatialite_osm_map makes me 
think that perhaps it is SQLite that does not scale up well.
