In the Rx bulk path, packets which are taken from the HW ring, are first copied to the stage data structure and then later copied from the stage to the rx_pkts array. For the number of packets requested immediately by the receiving function, this two-step process adds extra overhead that is not necessary. Instead, put requested number of packets directly into the rx_pkts array and only stage excess packets. On N1SDP with 1 core/port, l3fwd saw up to 4% performance improvement. On x86, no difference in performance was observed.
