Hi list,

just wanted to ask what is a "good/reasonable" value for the shared_bufferes variable. Right now i set it to 64000 on a windows 2003 server with 1GB ram and 3.2 GHz which runs as file server (for only a small number of users) and db server.

Thanks

settings section there.

Re: Shared buffers

Note that starting in 8.0/8.1, you can sometimes get very large gains
by setting shared_buffers very high; 1/2 of memory or more.
