Hi All, I am running an application, which connects to the postgres database at initialization time and perform the database operations like Select/Update. Database queries are very simple. On analyzing my application through Quantifier( Performance analyzing tool), I found the most of the time my application is waiting on recv, waiting for Database response. When i run Vacuum on perticular tables, i observed that performance improoves drastically. So please tell me how can i improve database performance through configuration parameters. I had tried to change parameters in postgresql.conf file but of no avail. Now i am trying to Auto Vacuum, but don't know how to run Auto Vacuum. Please help me to solve these problems. Thanks in advance.
