1-2 second delay on all commands over network

I am coding a small Visual Basic app using ODBC and ADO to connect to
a Postgres 7.3 database running on a RedHat 9 server. The issue I am
having is a small delay of 1-2 seconds for every command I issue in
the application. 2 seconds to connect then 2 seconds to query...about
2 seconds with every command. The app has a few simple queries when it
starts but takes a solid 10 seconds to first open because of these
delays.

The server is already being using as a web server and the speeds on
the queries that PHP makes is great.

Any suggestions would be greatly appreciated.

What does pg_hba.conf look like?  It is possible that it is trying to do
an ident lookup, failing that, and falling back to password or
something.

Cheers,

The applicable line in the pg_hba.conf file is

host <<database_name>>, <<database2_name>> <<username>> 192.168.0.0
255.255.0.0 password

The connection is made via the PostgreSQL ODBC driver from on Win2k
machine with a Linux account username and password.

The connection command from Visual Basic is dbSG.Open
"DSN=postgreSQL;UID=<<username>>;PWD=<<password>>;Database=<<database_name>>"

It turns out ODBC was doing some traces on my queries. I uninstalled
and reinstalled the Postgres driver and turned off tracing.
