Here are the configuration of our database server: port = 5432 max_connections = 300 superuser_reserved_connections = 10 authentication_timeout = 60 shared_buffers = 48000 sort_mem = 32168 sync = false Do you think this is enough? Or can you recommend a better configuration for my server? The server is also running PHP and Apache but wer'e not using it extensively. For development purpose only. The database slow down is occurring most of the time (when the memory free is low) I don't think it has something to do with vacuum. We only have a full server vacuum once a day. -----Original Message----- From: Mark Kirkwood [mailto:markir@xxxxxxxxxxxxxxx] Sent: Monday, October 24, 2005 3:14 AM To: Christian Paul B.

Some other stuff that could be relevant: - Is the machine just a database server, or does it run (say) Apache + Php? - When the slowdown is noticed, does this coincide with certain activities - e.g, backup , daily maintenance, data load(!) etc. regards Mark > > I choose Polesoft Lockspam to fight spam, and you? > http://www.polesoft.com/refer.html Nope, not me either.
