When ethernet throughput degrades it can be caused by many factors like the stream sending the packets slowing down, or transmit errors causing retransmission of packets. Often once there are errors, they grow exponentially because of retransmission etc. You should try to isolate the exact conditions you have when you see the traffic flow degrade. -Derek -- This message has been scanned for viruses and dangerous content by MailScanner, and is believed to be clean.
