I'm sure there are others with more experience on this, but if you don't need failt tolerance, a bunch of fast disks in striping-mode (so-called RAID-0) on seperated channels (eg. different PCI-Express channels) would be my first step. Alternatively, if you don't care if the data is actually stored, couldn't you process it with a program that does a checksum over the data transmitted and then ignores/forgets it? (eg. forget about disk-storage and do it all in memory?) -- Joost -- Sent via pgsql-performance mailing list (pgsql-performance@postgresql.org) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-performance
