Here are the results I am getting with a Cisco 10G VIC adapter. All tests are from the guest to an external host.
virtio-net-limit-xmit-polling/base: TCP_STREAM: 8089Mbps TCP_MAERTS: 9334Mbps virtio-net-limit-xmit-polling/v0 TCP_STREAM: 8004Mbps TCP_MAERTS: 9338Mbps virtio-net-limit-xmit-polling/v1 TCP_STREAM: 8028Mbps TCP_MAERTS: 9339Mbps virtio-net-limit-xmit-polling/v2 TCP_STREAM: 8045Mbps TCP_MAERTS: 9337Mbps For the TCP_STREAM tests I don¹t get consistent results. Every run gives me slightly different results. But its always between 7900Mbps to 8100Mbps. But I also see this with the base kernel so its not related to these patches.
