Flow director not spreading the flows on processors

Hello,

 

I am trying to evaluate Intel's flow director technology on a system with a Xeon E5-2643 and 4x10G XL710 Adapter.

 

The traffic is generated with nuttcp from client1 to server1 and from client2 to server2 (See attached document).

 

I was expecting Flow Director to pin each flow (different 5 tuples) on a dedicated processor ... but it does not seems to be the case. The flow are always be handle by the same processor.

 

Am i missing something ? shouldn’t the second flow be on a different queue (processor) ?

 

Thanks
