Another pointer: How many VACUUMs does osm2pgsql trigger during import and filling the own tables? I also registered some slowing down with my own application when it comes to VACUUM. And I also read some mailings about this issue on the PG-MLs. AFAIR osm2pgsql does not timestamp its steps so it is probably a little difficult to hunt the real timeconsumer down.
