Hi All, the scenario appears to involved DPDK application in the guest. Is that correct?
For linux applications in the guest iperf3 default tcp throughput test, I have seen much increased performance in with indirect descriptors enabled in the dpdkvhostuser ports. This setting is available with >=DPDK16.11 in the host. https://mail.openvswitch.org/pipermail/ovs-dev/2017-March/329227.html I have not yet had the chance to test with dpdk applications in the guest but when I get results with that I will post them here. /Billy -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1668829 Title: Performance regression from qemu 2.3 to 2.5 for vhost-user with ovs + dpdk To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/qemu/+bug/1668829/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
