Remote access to Postgresql slow

Hi,

I have a Centos 6.2 Virtual machine that contains Postgresql version 8.4 database. The application installed in this Virtual machine uses this database that is local to this Virtual machine.  I have tried to offload the database, by installing it on a remote Virtual machine, on another server, and tried to connect to it from my local Virtual machine. The application configuration remains the same, only database is offloaded to a remote Virtual machine on another server and the connection parameters have changed.  The connection is all fine and the application can access the remote database.

I have observed that the Postgresql is responding extremely slow.  What should I do to improve its performance?

Please suggest.


Kind Regards,
Manoj Agarwal
