Here is an example of iperf from the server side: 

% iperf -s -w lM -1 16k

Here is an example of iperf from the client side:

% iperf -c <ipAddr of Server> -w 1M -P12 -l 16k -P<number of threads>

Note the following:



PCIe x8 provides optimal performance for 10GbE.



MSI and MSI-X interrupts perform better than legacy interrupts.



Linux kernel version 2.6.15 and higher provide better performance 
optimization.



Check CPU utilization on the host for CPU-bound bottlenecks.
