    关于 cyw43907测试iperf

      我在测试iperf的时候,开发板作为client ,udp传输方式,最高52Mbps,但是换成tcp传输的话,就变成5Mbps了。

       

      开发板作为server的话,udp和 tcp都是5Mbps。

       

      想请问下,关于开发板cyw954907的iperf如何测试?测试性能大概是多少?

          Hi :

               please update which app you are using now and the command for T/P test.

          our T/P value should be larger than the value you provided.

            我用的是WICED-Studio-6.2.1.2-IDE-Installer

            T/P值大概是多少?

                  Hi :

                       In my test set another side is a 1G ethernet port in a PC, not a wireless card.

                  and 34.8 Mbits/sec is a reasonable value if AP is not good enough , or environment is noisy .
