I have this customized device that is using an AM5716 CPU and installed with OpenWrt snapshot r14777-c4ab1b7dd9, I tried to run iperf3 test on it and my PC in order to test the maximum throughput.
on the device: iperf3 -s
on my PC: iperf3 -c 192.168.1.1
Result: around 790Mbps ~ 830Mbps
on my PC: iperf3 -c 192.168.1.1 -R
Result: around 940Mbps
Any idea why this happens? Is there any way to boost up the throughput of the device?
