Ethernet throughput: Upload speeds are slow

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.
