4 Performance test results using Mellanox ConnectX5 2p100GE are reported for
5 2-Node Xeon Cascade Lake physical testbed type present in FD.io labs. For
6 description of physical testbeds used please refer to
7 :ref:`tested_physical_topologies`.
12 Mellanox ConnectX5 NIC settings are following recommendations from
13 [DpdkPerformanceReport]_, [MellanoxDpdkGuide]_ and [MellanoxDpdkBits]_.
19 $ ethtool -A $netdev rx off tx off
21 - Change PCI MaxReadReq to 1024B for each port of each NIC:
24 $ setpci -s $PORT_PCI_ADDRESS 68.w=3BCD
26 - Set CQE COMPRESSION to "AGGRESSIVE":
29 $ mlxconfig -d $PORT_PCI_ADDRESS set CQE_COMPRESSION=1
31 Mellanox :abbr:`OFED (OpenFabrics Enterprise Distribution)` driver of version
32 4.6-1.0.1.1 is installed and used to manage the NIC settings.
