How to display DELTA values (bytes sent/recvd since last refresh) on Connection lists
Enter the DELTA ON command on the command line while displaying connection lists /CONNC, /CONNNT or /CONNTR to display the Bytes In/Out Delta.
DELTA ON changes the values displayed in the Bytes In and Bytes Out columns to be the bytes sent and received on the connection since the list was last refreshed.
You can press F6 to refresh the list.
DELTA OFF reverts to the normal display, where Bytes In and Bytes Out represent the total bytes since the connection began.
