> RAID1 2 disks OS, pg_xlog > RAID 1+0 4 disks pgdata Looks like the consensus is RAID 1 for OS, pg_xlog and RAID10 for pgdata. Now here's another performance related question: I've seen quite a few folks touting the Opteron as 2.5x faster with postgres than a Xeon box. What makes the Opteron so quick? Is it that Postgres really prefers to run in 64-bit mode? When I look at AMD's TPC-C scores where they are showing off the Opteron http://www.amd.com/us-en/Processors/ProductInformation/0,,30_118_8796_8800~96125,00.html It doesn't appear 2.5x as fast as the Xeon systems, though I have heard from a few Postgres folks that a dual Opteron is 2.5x as fast as a dual Xeon. I would think that AMD would be all over that press if they could show it, so what am I missing? Is it a bus speed thing? Better south bridge on the boards? -- Jeff Frost, Owner <> Frost Consulting, LLC http://www.frostconsultingllc.com/ Phone: 650-780-7908 FAX: 650-649-1954
