Quick reference, you get one of these: http://www.aberdeeninc.com/abcatg/Stirling-X888.htm with dual 2.26GHz Nehalem CPUs, 48 Gigs ram, and 48 73K 15kRPM Seagate barracudas for around $20,000. That's the same cost for a single oracle license for one CPU. That's way overkill for what you're talking about doing. A machine with 8 or 16 disks could easily handle the load you're talking about. -- Sent via pgsql-general mailing list (pgsql-general@postgresql.org) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-general
