@DemiMarie I would need to spend some time to reproduce the benchmarks, but from what I remember, roughly: - vanilla firecracker: 500Mbps of UDP traffic max - firecracker + vhost-net:...
Apologies, I didn't answer the io_uring question: io_uring on tap is not faster than tranditional read/write on tap. See [tap blog post](https://blog.cloudflare.com/virtual-networking-101-understanding-tap/). Multiqueue without vhost-net makes no sense to me....

@wkozaczuk your memory math is wrong. But I also think VIRTIO_NET_F_MRG_RXBUF is important. Without MRG_RXBUF we have the following cases: * offloads enabled * offloads disabled Offloads disabled is "easy",...
