You probably want to increase shared_buffers by quite a large amount and maybe make work_mem not quite so big. If you have 2GB of memory you might set shared_buffers to 1GB, work_mem 16MB, maintenance_work_mem 64MB? ...Robert -- Sent via pgsql-performance mailing list (pgsql-performance@xxxxxxxxxxxxxx) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-performance
