How to speedup inserts via ADO ?

Hi all !

Inserts via ODBC are a lot slower than via native psql connection.
For instance, I have a very basic insert statement that inserts one row
in a table.
If I execute it 1000 times in pgAdmin, it returns in 718ms.
If I execute it via ADO (with a direct query : Connection.Execute
"INSERT INTO..."), it takes 15s to complete.

I checked psqlODBC's commlog, but all I see in it are the INSERT
statements that I issued. So there must be a lot of overhead somewhere,
but I don't understand where it comes from, and more important I don't
understand how I could get rid of it.

Are there some connection parameters that I could use to speed things up ?

Thanks a lot for helping !
