Figure 5-6 Packet Loss Test - Results
5.7 Throughput
The Throughput test calculates the maximum data rate to and from a specific endpoint, designed as a
basic upstream/downstream capacity measurement. The target endpoint of the test must be a computer
running a webserver application that is specifically configured for this test. For more information, see
Throughput server setup on page 5-12.
Note the following:
• While running this test, keep in mind that throughput in any direction can never be greater than the
slowest segment in the path. Therefore, for proper interpretation of results, you should have some
awareness of which segment is expected to have the lowest throughput under normal conditions.
• This test is based on a transfer of data over a TCP connection. TCP data rates may vary dynamically
during the course of transmission; therefore, results between different file sizes and different tests
may be inconsistent. In particular:
– Large file sizes may indicate a higher data rate than smaller sizes, because the endpoints will
have more time to optimize the TCP link.
– TCP involves retransmissions of lost data, which can have a varying effect depending on what
stage(s) of the file transfer that the retransmission(s) occur. For example, if loss occurs later in the
transfer when the TCP window size may be allowing larger units of transfer, a retransmission will
be more costly to the overall data rate.
In summary, while this test may be useful for determining a baseline for the user experience, it cannot
provide a precise or consistent data rate measurement at the lower data link layer.
