Hi, I'm new to dpdk - played with execution_path, l2fwd and l3fwd examples. I'm using 82599ES intel dual 10G interface on Xeon X5650 2.67GHz.
I got the following strange results with my tests: 1) Sending 10G in port 0 only - stand in line rate (no misses). 2) Sending 10G in port 1 only - stand in line rate. 3) Sending 20G (ports 0 and 1) and preform rte_eth_rx_burst() on both ports with single lcore - stand in line rate . 4) Sending 20G (ports 0 and 1) and receiving each port in different lcore - can't stand in line rate (rx misses). I do not transmit the packets - just call rte_eth_rx_burst(), increase the counters and free the mbuf. All the lcores are on socket 0 (the one closer to the interface). Any idea? How can i get line rate with multi cores? Thanks, Ran.
