Hello, my impression has been that in the past, there has been a general semi-consensus that upping shared_buffers to use the majority of RAM has not generally been recommended, with reliance on the buffer cache instead being the recommendation. Given the changes that have gone into 8.3, in particular with regards to minimizing the impact of large sequential scans, would it be correct to say that given that - enough memory is left for other PG bits (sort mems and whatnot else) - only PG is running on the machine - you're on 64 bit so do not run into address space issues - the database working set is larger than RAM it would be generally advisable to pump up shared_buffers pretty much as far as possible instead of relying on the buffer cache? -- / Peter Schuller PGP userID: 0xE9758B7D or 'Peter Schuller <peter.schuller@xxxxxxxxxxxx>' Key retrieval: Send an E-Mail to getpgpkey@xxxxxxxxx E-Mail: peter.schuller@xxxxxxxxxxxx Web: http://www.scode.org
