Apart reading carefully the documentation of the drivers at
http://www.gdal.org/ogr/drv_osm.html and http://www.gdal.org/ogr/drv_pg.html to
be aware of the various optimization hints, nothing comes to find. There have
been several optimization passes and improvements done with Jukka's feedback in
the last few months, so now I consider the gist of the developmement phase to be
done.

Yes, sure. Feedback welcome. Note that the driver hasn't specifically been
developed to compete with osm2pgsql (for example, the OGR OSM driver, or more
exactly the OGR model, cannot deal with OSM diff files), but more to address the
capability of reading/converting "modest" sized .osm/.pbf files with little
"infrastructure".
