Subj:   Re: Slow Responding State - looking for bottleneck
 
From:   Robert D Meunier

In addition to the Teradata NIC being degraded it's possible that the whole sub-net is degraded. Some switches/hubs have to degrade to the lowest common denominator. If someone else has connected to your sub-net at half-duplex or even 10mb/sec the whole sub-net may have been degraded to accept this connection.

Another possibility is that a router table (or the router itself) has been changed or a router is going bad.

You didn't mention what the network destination is, but it's also possible that it's a problem with the NIC on the target server/pc. It could also be a performance issue with the destination. If it's not a dedicated machine it's possible that it has all of a sudden become over worked.

I'd:

1) Check the Teradata NIC as already suggested

2) Check the destination machine's NIC and/or performance on the destination machine. If possible change the destination machine and see if performance is better.

3) Contact your network support people and have them check their equipment. If nothing else they should be able to snoop your line and see what the throughput is.
