Is the FastLoad running directly on one of the database (TPA) nodes or on a separate application server? Client CPU usage appears not to be an issue (1.44 seconds). Have you looked at disk I/O and network throughput on the box running FastLoad? And network througput on the Teradata node(s)?

Mismatched ethernet speed or duplex settings between an adapter and a network switch can result in a connection that appears to work for trivial requests but is extremely slow when handling large data volume.

As an aside, note that FastLoad 7.5.0 dates from 2002 (TTU6.2). I don't think really that's causing your problem, but you might want to consider upgrading.

Thanks Fred.

FastLoad is running on a separate application server and not on the TPA node.
The application server is in a different network and the TPA node in another. Both the networks are configured for 100Mbps transfer speeds.

It can well be a network issue, which i am investigating. Meanwhile, any suggestions and views are welcome.

Thanks,


Kir Bojo..

Hi All,

Thanks for your help.

The issue is resolved. The cause of the delay was due to network and switches.

Thanks,



Kir Bojo..
