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
