What's the platform exactly (hardware and OS)?
Hardware: http://www.appro.com/product/server_1142h.asp - SCSI version, 2 x 146GB 10k rpm disks in software RAID-1 - 32GB RAM
OS: Linux 2.6.10-rc3, x86_64, debian GNU/Linux distribution
- CONFIG_K8_NUMA is currently turned off (no change, but now all CPUs have ~25% load, previously one was 100% busy and the others idle)
- CONFIG_GART_IOMMU=y (but no change, tried both settings)
[other kernel options didn't seem to be relevant for tweaking at the moment, mostly they're "safe defaults"]
The PostgreSQL data directory is on an ext2 filesystem.
