Subject: [dpdk-users] Performance of VF and DPDK port on multiport card
Date: Tue, 28 Apr 2020 13:46:17 -0700 [thread overview]
Message-ID: <CAKrN9FH6N0z0H3WArrNa6d-4WxZiVBpJsiUsVx-+OPPe8_gaCQ@mail.gmail.com> (raw)
Hi All,
I have 4 port card X710 card(i40e driver), on 3 of them i have configured
SRIOV and using one physical port bound to ovs-dpdk. I am observing some
strange behaviour with performance. If i run traffic on SRIOV VFS and DPDK
port , performance is better on SRIOV VFS.
If I remove DPDK port and run traffic, SRIOV VFS starts dropping the
packets.
Card is running in multimode-driver , 3 kernel and 1 OVS-DPDK.
What exactly OVS-DPDK(i40epmd)/DPDK sets in the global pnics card
registers that is causing better performance of the overall card ?
