Got it. Just to clarify, does tapv2 use vhost-net backend? Is is correct/sufficient way to use it? create tap id 0 host-ip4-addr 10.20.2/24 host-if-name testtap Thanks On Sat, Oct 27, 2018 at 1:49 AM Damjan Marion wrote: > > > Tap (with vhost-net backend) is faster and it is real interface from

If you are interested in performance, i suggest using tap interface instead of af_packet. With tap (by using vhost-net backend) there is no memcpy involved, kernel puts buffer data straight into VPP buffers... -- Damjan > On 30 Oct 2018, at 13:07, Xuekun wrote: > > Hi, All > > Recently I

Hi, All Recently I found a big performance difference (~5Gbps vs. ~300Mbps by iperf3) between two settings, which AF_PACKET related. The testing topology: Two servers are directly connected through 10G link; One is running VPP on the 10G NIC and AF_PACKET interface. And the iperf client
