Hello, I've finally doubled up RAM to 32 GB for my Quad core CentOS 6.3 server and have changed postgresql.conf to max_connections = 100 shared_buffers = 4096MB work_mem = 16M But don't see any speed improvement and also 27 GB of memory aren't used.... Please see more info + vmstat at http://serverfault.com/questions/433281/doubled-up-ram-to-32-gb-now-how-to-speed-up-a-lapp-server Thank you for any suggestions Alex -- Sent via pgsql-general mailing list (pgsql-general@xxxxxxxxxxxxxx) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-general
