[dpdk-dev] Receive packet one by one instead of a bulk of 16

hi all,


    In "testpmd", the default nb_pkt_per_burst value is 16, that is, receive 16 packets one time and then forward.
    Now, I set nb_pkt_per_burst=1, and after the packet received, delay 50us, because I have to add some packet processing steps between receive and transmit. However, in this situation, I lost 20% packets. How could this happen? And what should I do to have an effect?
    Any help will be appreciated.


Best Regards.
Maria
