I have a machine (ubuntu 12.04) with 2 nics and I am trying to send data
between the two. However, when I iperf from one to the other, the OS is
optimizing it and the data is never actually being sent out on the network
(I want it to go through the switch).
Is there any way I can move one of the physical interfaces into a network
namespace and then try to iperf from there?
Any help would be greatly appreciated!
