Hello Rainer,
The database computer is connected via a 2MBit SDL connection. I myself have

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.
Harald
