See slide 32. This is without vhost-net.
Thanks. Do you also have latency numbers?
No. Copying Chris. This was with the tx mitigation timer disabled, so
you won't see the usual atrocious userspace virtio latencies, but it
won't be as good as a host kernel implementation since we take a
heavyweight exit and qemu is pretty unoptimized.
It seems like there's definitely still potential for improvement
with messages<4K. But for the large messages they indeed
look rather good.
There's still a lot of optimization to be done, but I hope this proves
there is nothing inherently slow about virtio.
