I think it should be very easy to make this model to be multithreaded and use more CPU cores. I think, the only way to achieve this is to use multiple connections to the database. One connection to select the table_name and than, for every table_name, a own connection to the database to select and write the data to files. Andreas -- Really, I'm not out to destroy Microsoft.
