Hi Hillary, I'd suggest around 1000 to 2000 shared buffers and bump your max connections to at least 64.
Make sure you're kernel allowed enough shared memory for the above (2000 * 8k = 16MB) Chris ----- Original Message ----- From: "Hilary Forbes" <[EMAIL PROTECTED]> To: <[EMAIL PROTECTED]> Sent: Tuesday, July 01, 2003 8:10 PM Subject: [PERFORM] Version 7 question > I'm just trying to improve performance on version 7 before doing some tests and hopefully upgrading to 7.3. > > At the moment we have > B=64 (no of shared buffers) > N=32 (no of connections) > in postmaster.opt which I take it is the equivalent of the new postgresql.conf file. > > From all that is being written about later versions I suspect that this is far too low. Would I be fairly safe in making the no of shared buffers larger?
