The Compaq servers you indicated use the smart array controller which is
very very slow in storing data into hard disks. Are you using the RAID?
I suggest you to buy a controller with a larger write cache (the smart
array controller does not have w-cache)... You should note a large
performance progress...
Also do not forget to set fsync to false and to use the COPY command
whenever is possible...
Bye!
