IAC, it seems silly to run a robot through the Web interface if its internal. They should be running hte thing off a service or a standalone process that runs in the background instead of tieing up the Web application.

So, basically, the 15 to 20 MB files received are being processed in sequence and that will create numerous new records in tables and several adjustments on existing records.
