The TCP Efficiency Report shows the total efficiency of all TCP connections over time. The report can be viewed by applications, or internal or external hosts. You can drill into particular apps or hosts to view the efficiency for particular traffic. This report can answer questions such as "Are we experiencing network delays due to TCP inefficiencies? Is a particular application or host having troubles due to retransmissions?"
TCP Efficiency is calculated using the formula below:
TCP Efficiency = (Total Bytes - Bytes Retransmitted) / Total Bytes
The table below shows both retransmitted bytes and efficiency per Application or Host. Each item in the table below can be drilled down to view TCP Efficiency details and a graph for that item.
Where do I find this report?
Go to Monitor > Service Levels > TCP Efficiency.
