Timings and sizes

23 October 2022

When starting out with osm2pgsql there is often the question: How large is the resulting database going to be and how long will the import take?

The invariable answer is, of course, “it depends”. But that’s not very useful. Using the new server sponsored by FOSSGIS we ran lots of imports with different configurations and different input data from the Switzerland extract to the full planet and wrote down the results in a new “Sizing” appendix in the manual. This will give you at least some idea on what to expect.
