I have at home two TL-PA7020 (AV1000) at home, one of them connected to the router, another to a computer. Using iperf3, I get a bandwidth of around 150 Mbps to send from the computer to the router and the same from the router to the computer.
I read how powerline works and what the 1000 Mbps advertised speed actually mean. Correct me if I'am wrong, but from my understanding, the theoretical maximum speed is 500 Mbps one way and the same the other way. Because of wiring quality, distance, etc. between the two adapters, you will get a lower speed.
I used the software from TP-Link "tpPLC" to get information about the two adapters. It reports to me that the "Powerline Rate" between the two adapters is around 325 Mbps (350 Mbps one way and 300 Mbps the other way). Right in the software, the definition of "Powerline Rate" is:
Powerline rate here means the transmission capacity of your electrical wiring and differs from the actual data transfer rate of your terminal
So it seams that I should get around 300 Mbps, which I don't. Is this normal?
(I made sure it was not the computer adapter the problem. I am 99 % sure it is the powerline the bottleneck. If anyone wonder how I tested this, I have more then one computer on each side of the powerline, so I can test them without going through the powerline adapter.)
EDIT:
Here is iperf3 output if it can help :

iperf Done.
The iperf3 log of router to computer is similar. If it is needed, tell me in the comments and I will add it.

I believe wireline is a lot like wifi in as much as quoted speeds are theoretical maximums and actual performance will depend on noise fed back by other devices, distance, smoothness of power and things like fuses & rcd'd – davidgo – 2017-08-27T16:34:35.520
