Hi, I did a full (osm2pgsql) planet import on a standard Ubuntu Jaunty system and it took 1794 minutes. Then I upgraded to Postgres 8.4 (backported from Karmic) plus PostGIS 1.4 (home-built package), and re-tried the import: 2028 minutes (that's 13% performance loss).
Can anybody confirm this measurement, or even suggest what the reason might be? I used the same postgres.conf for both databases. I noted that Postgres 8.4 produced 25% more data in the pg_xlog directory than 8.3 did, could that hint at the reason for the difference?
