Subject: [dpdk-dev] Why MLX4 can only generate 6Mpp/s (64B pkt) by one core?
Date: Tue, 10 Jan 2017 12:51:04 +0800	[thread overview]
Message-ID: <CAOwUCNtj9aF3R9B7OPdCrajNF_-eJcaS7ihs8tGR07h9-0dANA@mail.gmail.com> (raw)

Dear all,

My  Mellanox 3 Pro can only generate packet at maximum of 6Mpp/s (64B) by
one core. This is too slow for a 40Gbps port. Could anyone give me a hint
please?


Configuration:
Followed: http://dpdk.org/doc/guides/nics/mlx4.html

1. install MLNX_OFED_LINUX-3.4-2.0.0.0
2. Added CONFIG_RTE_LIBRTE_MLX4_PMD=y in .config
3. make DPDK 16.07.2
4. Closed Dell S6000 swith flow control (both rx,tx)
5. Made sure all ports are in 40GBE mode


With my own pkt-gen and DPDK-pktgen, both generate at 6Mpps of 64B pkt by
one core, which is so slow, since I can generate 14Mpps via an Intel X520
10G interface.

Thanks.
