Hi Mike, I did a detailed comparison and found that the issue is actually with the performance of mirror-to itself, not with virtio-user. Even when using mirror-to directly, there is still a significant performance degradation. ovs-tcpdump -i vh-userclient-08a1f95c-3b --mirror-to tap1 -w a.pcap ovs-tcpdump -i vh-userclient-08a1f95c-3b -w b.pcap Jun Wang
