Example: Diagnose Slow Connection Response Time
A connection is exhibiting slow response time. To try to find out the cause of the problem, you enter I next to the connection. The displayed information can provide hints as to why the connection is slow, for example:
Indicates whether transferred packets are fragmented. If a packet is too large and becomes fragmented, it needs to be reassembled at the destination. The process of fragmentation and reassembly can contribute to poor response time.
Displays the number of retransmissions. When packets are lost, the lost segment or segments are retransmitted. Retransmissions can contribute to poor response time.
Displays the size of the buffer that is available to receive data. The size changes as data is moved into or out of the buffer. If the receiver advertises a window size of 0 (a closed window), it stops the data transfer. Closed windows can contribute to poor response time.
You find that some of the information warrants investigation at the packet level. For example, you want to find out which packets are fragmented. You can use SmartTrace line commands to trace the packets flowing through the connection.
