The statistics window allows you to view details of the rule, including start time, amount of traffic processed and current queue usage.
Current Transfer Rate
Displays the current usage for the rule. This value is also used internally by the server when allocating free bandwidth. It is calulated by taking the average of the last three seconds of data transfer.
Displays the number of packets that are currently being held, waiting for available bandwidth so that they can continue to their destination. For most networks the average (and maximum) size of a packet is around 1500 bytes. So a queue of 20 will take up 30K of kernel memory.
Shows the date and time that the rule was created.
Shows the total amount of data transferred by the rule since its creation.
