I am using PostgreSQL 8.3.7 on a dedicated IBM 3660 with 24GB RAM running CentOS 5.4 x86_64. I have a ServeRAID 8k controller with 6 SATA 7500RPM disks in RAID 6, and for the OLAP workload it feels* slow.... My current performance is 85MB/s write, 151 MB/s reads
I get 193MB/sec write and 450MB/sec read on a RAID10 on 8 SATA 7200 RPM disks. RAID10 seems to scale linearly -- add disks, get more speed, to the limit of your controller.
