The Intel NIC benefits from a multiqueue system. The RX/TX traffic can be load-balancedon different interrupts. In our case, this permit to handle a part of the flow on eachCPU. One really interesting thing is that the load-balancing can be done with respectto the IP flows. By default, one RX queue is created per-CPU.
