The hardwares are clearfog A1 board with armada 388 and WLE900VX (QCA9880). The OpenWRT trunk is running on it. At first I did UDP throughput test ( WDS AP <---> WDS Client ) with iperf3 server on the WDS AP. The throughput is approx 630 Mbps. But if the server sends the data, the throughput will rise to 700 Mbps. I did the bidirectional test for many times. The UDP data transferring from AP side always has 70 - 80 Mbps more throughput. In the same situation, I did UDP throughput test between PC and WDS AP ( PC <---->WDS Client <----> WDS AP ) . The PC is connected with the WDS client via GbE port. I have found a more interesting result. The data throughput is about 678 Mbps when the data is transmitted from AP to PC. There is almost no performance loss. But the throughput is only about 425 Mpbs from PC to AP. Can anyone give me some advises or some info about the reason and how to improve the transmitting performance from PC to AP side. Thank you.
