Hi, I am doing experiments about packet classification algorithm and I found I always get RX Error when the throughput is too high, so I did the following experiments.
There are two PC servers (A and B), each of them has a Intel 82599ES 10G with two ports(1 and 2). And they are connected to each other. I simply run pktgen on both server. When I start one of the server and let it generate 10Gb/s traffic each port, which is start A1 and A2. I can receive the 10Gb/s traffic on the other server's every port. When I start one port of the two servers and let them generate 10Gb/s traffic to each other, which is start A1 and B1. Both the port show that they can receive 10Gb/s and send 10Gb/s traffic. But When I start both port on both server, which is start A1, A2, B1, B2, each port shows it can generate 10Gb/s but it can only receive 6.7Gb/s traffic and the left 3.3Gb/s are considered RX Error. When I stop one of the ports, which is start A1, B1, B2, On server A I receive 8.1Gb/s on A1, 8.4Gb/s on A2, while A1 is sending 10Gb/s traffic, the traffic left is considered RX Error. I receive 10Gb/s traffic on B1, sending 10Gb/s traffic on B1 and B2. My parameter is -c 0xff -n 4 -- -P -m "[1:2].0, [3:4].1", but it won't change when I assign more lcore on RX queue. I'm thinking it maybe is the parameter problem, such as the Hugepage or others, is there any solution or advices?
