Hello Rainer,
The database computer is connected via a 2MBit SDL connection. I myself have a
768/128 KBit ADSL connection and pinging the server takes 150ms on average.
I do not have a solution, but I can confirm the problem :)
One PostgreSQL-Installation: Server 8.1 and 8.2 on Windows in the central; various others connected via VPN. Queries are subsecond when run locally (including data transfer), and up to 10 seconds and more via VPN, even in "off-hours"
The data-transfer is done via PG-Admin or via psycopg2 Python-Database adapter; nothing with ODBC or similiar in between.
I did not find a solution so far; and for bulk data transfers I now programmed a workaround.
