Using the Theoretical throughput calculations in Table 1 you can compare the results with the measured to give an indication of the difference between expected and measured. Remembering that the theoretical calculations are best case possible results

Table 1

In the command line for the Client mapping we established the Server IP address followed by the –w 65535, -w is the window size and the maximum TCPIP window size is 65535bytes.

Another entry that can be added is –t <seconds> to run the test for a specific time period. Example of this is in figure 5 where the same test is run for 30 seconds.

JPerf Application

Jperf is a graphical interface that runs over the top of Iperf. It will display a graph result from the Iperf test.

To run Jperf open a CMD prompt and change to the “jperf-2.0.2: directory and run the “Jperf” application as shown in Figure 6.

Figure 6

Followed by entering in “Jperf” at the prompt and pressing enter. The CMD screen will disappear and the Jperf Screen will appear as seen in Figure 7.
