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! -- Doct. Eng.
