PingFill Throughput Test

The PingFill throughput test is included in special versions of the KarlNet configuration utility, and is useful in testing the overall throughput of your network connections between two points.

In order to test network throughput, the Ping Fill Test dynamically fills the network connection with ICMP Echo (ping) packets and waits for the responses from the target station. Since each packet sent is echoed back to the sender, this tests the overall throughput in both directions.

The PingFill test is useful for testing network throughput between any KarlNet unit and any other computer connected to the unit. Special care must be taken in using this test, however, as it completely saturates the network with packets, without overloading systems connected to the network.

The speed at which the target station responds to the ICMP Echo packets is crucial to correctly assess the speed of the link. The IP stacks in some PC operating systems, such as earlier versions of Microsoft Windows, often do not respond quickly enough to the ICMP Echo packets to obtain an accurate assessment of your network throughput. When running the Ping Fill test to some systems, your results may be slightly lower than normal throughput.
