I have been doing some preliminary testing using the iMX6Q Sabre Platform. Using iperf, I am getting speeds of around 425Mbps, which is expected for gigabit Ethernet. However, on uploads, I am only seeing speeds at around 60Mbps. To restate, here are the commands I am using:
iperf -c <server_ip> -i 2 -p 50000 -t 20 ====> ~425Mbps
iperf -s -i 2 -p 50000 ====> ~60Mbps
Is this the expected behavior for the Ethernet controller on this board? Is there a patch planned to increase performance? I am using the Linux BSP LTIB L3.0.35_4.0.0_130424.
