Your RAM access tops out at 16 processors. It appears that your processors are spending most of their time waiting for and contending for the RAM bus. I have gotten machines in where moving a jumper, flipping a DIP switch, or changing BIOS options from the default made a big difference. I'd be looking at the manuals for my motherboard and BIOS right now to see what options there might be to improve that. -Kevin -- Sent via pgsql-performance mailing list (pgsql-performance@xxxxxxxxxxxxxx) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-performance
