Hello

Someone can say me if the Transfert RAte is limited at 300mo or like the Bananapi m64 a true Gigabit.

Thanks

If the A31s is anything like the gigabit on the A20, it's limited to around 400mbit due to internal bus limitations.

Nope, for A20 (BananaPi M1) performance see here and for the M2 just search for 'iperf' in this thread there: 

 

'Funny': By searching for M2 iperf results I stumbled accross this here again: https://groups.google.com/d/msg/linux-sunxi/sMMqCjUfoLE/RXYJwz0U_C4J

 

I just ran iperf3 as server on an XU4

All boards are running at max speed via cpu-freq

What's wrong with my A20 based Cubietruck? It's running Armbian 5.32 with 4.8.4 kernel
