Message-ID: <20000228103056.I606@reptiles.org> Mime-Version: 1.0 Content-Type: text/plain; charset=us-ascii X-Mailer: Mutt 1.0i Sender: owner-freebsd-smp@FreeBSD.ORG Precedence: bulk X-Loop: FreeBSD.org i poked about on the freebsd website, and found that the information about SMP appears to be somewhat stale. i'm not on freebsd-smp, so direct replies would be appreciated. i'm running a fairly large/busy postgresql database. i'm considering moving it to a multi-processor (start with 2, maybe add more) machine. i'm considering the following for 3.4-STABLE (or 4.0-RELEASE): ASUS (P2B-DS or P2L97-DS) 512M RAM 1 x scsi drive for OS/applications 5 x 9/18 gig U2W drives under vinum raid5 for data my understanding of the SMP stuff is that if the application is not multi-threaded, then SMP doesn't do much. my theory was that with a dual processor, each incantation of the application would fire up on alternating processors. is this correct? or is SMP effectively useless unless my application (primarily postgresql) is multi-threaded. -- [ Jim Mercer jim@reptiles.org +1 416 506-0654 ] [ Reptilian Research -- Longer Life through Colder Blood ] [ Don't be fooled by cheap Finnish imitations; BSD is the One True Code. ] To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-smp" in the body of the message
