I think the benchmark data is a prerequisite for merge consideration, IMO.

Do you have anything for us to look at?  I think comparison that show
the following are of interest:

throughput (e.g. netperf::TCP_STREAM): guest->host, guest->host->guest,
guest->host->remote, host->remote, remote->host->guest

latency (e.g. netperf::UDP_RR): same conditions as throughput

cpu-utilization

others?

Ideally, this should be at least between upstream virtio and vhost.
Bonus points if you include venet as well.

Kind regards,
-Greg
