The Data Transfer Time report shows the time it takes to transmit a complete response as measured from the initial to final packet. Data Transfer Time excludes the initial server response time and includes only Network Round Trip Time if there is more data to send than fits in the TCP window.
Factors affecting this time are response size, available bandwidth, network latency because of distance, some server processing, and interactions such as the number of round trips, and individual packet size between the application and the network.
Data Transfer Time is related to the number of network round trips required to deliver all data and the delay per round trip.

Might Indicate |
|
Increase in Data Transfer Time |
One of the following conditions:
Correlate a significant increase in Data Transfer Times with data volumes to determine if the increase is caused by larger amounts of data being transferred on the network or if there is a problem. |
|
Variations in Data Transfer Time by subnet |
Lack of bandwidth available to the region, retransmissions required to certain regions, and different uses of the application. |
