A basic Ubuntu Jaunty system with standard osm2pgsql from SVN, basic 
PostGIS tuning as per wiki pages (shared_buffers=448MB, 
maintenance_work_mem=256MB, logging and ssl and auto-vacuuming disabled).

The hardware was an i7-920 with 12 GB RAM and two 1.5 GB Seagate 
Barracuda disks - a standard Hetzner EQ6 system.

No special performance tuning or tweaking, but interested in hearing 
what others have tried with their PostGIS as well.

Bye
Frederik
