Hi,

I am not able to evaluate if your code is effective or not. However, I can
give you some numbers for comparison.

Test data http://download.geofabrik.de/europe/finland-latest.osm.pbf
- 322 MB as .pbf
- 770725 points
- 1778917 lines
- 3128 multilinestrings
- 2087911 multipolygons
- 6985 other relations

Command:
ogr2ogr -f gpkg finland.gpkg finland-latest.osm.pbf

Execution time on Windows laptop:
2 minutes and 20 seconds

If you experience some slower performance it is probably not because of
SQLite/GeoPackage as a format is slow but because something is not done in a
way that is not optimal for the format. Could you also define your source
data and the performance that you have measured?
