[Edited Message Follows] Dear vpp-dev teams,
I am a newbie in VPP. Many thanks to you all for making great Vpp. I have many applications in user space (written by java, C, python,...) and I want to connect those apps to VPP so what is the fastest way that VPP can support without changing the application? I tried with tap create by VPP and cross connect it to a physical NIC, NIC is binded by DPDK: vppctl create tap id 0 host-ip4-addr 192.168.56.110/24 ( http://192.168.56.110/24 ) gso vppctl set interface tap0 ip address 192.168.56.110/24 ( http://192.168.56.110/24 ) vppctl set interface l2 xconnect tap0 enp0s8 vppctl set interface l2 xconnect enp0s8 tap0 vppctl set interface state enp0s8 up vppctl set interface state tap0 up But the bandwidth are lower and latency is higher than when I use real NIC ( not using VPP). VPP is version 21.10, I use 4 workers. Server is ubuntu 20.04, tool test is Iperf3. Please help me , thank you very much.
