This is driving me crazy. A new server, virtually identical to an old one, has 50% of the performance with pgbench. I've checked everything I can think of.
The setups (call the servers "old" and "new"):
old: 2 x 4-core Intel Xeon E5620
new: 4 x 4-core Intel Xeon E5606
both:
memory: 12 GB DDR EC
Disks: 12x500GB disks (Western Digital 7200RPM SATA)
2 disks, RAID1: OS (ext4) and postgres xlog (ext2)
8 disks, RAID10: $PGDATA
Exact same model of disk, same on-board cache, same RAID-card RAM size, same RAID strip-size, etc.??
Cheers,
