Hi All, I have an extremely simple test - I have just one single DPDK EAL thread which pulls packets from one 10G port and just puts the packet exactly as is (no changes) on another 10G port - I get 9.5million pps, so far so good. So its like this
dpdk_rx dpdk_tx 9.5 Millionpps Now I do the below and the performance comes down to like 4 Million pps, less than half ! dpdk_rx rte_ring_mc_dequeue_bulk(my_ring1, my_array, nb_rx) dpdk_tx rte_ring_mp_enqueue_bulk(my_ring1, my_array, nb_rx) Note that I do nothing with the things I dequeue from the ring, I just enqueue it back. So is there any gotchas in using these rings ? I am sure I am missing something, it cant drop from 9.5Mpps to 4Mpps just because of a dequeue/enqueue ? Rgds, Gopa.
