+1. Connect two nic port directly, put nic2 into another namesapce and turn on the tso of this nic port by below cmds::
+
+    ip netns del ns1
+    ip netns add ns1
+    ip link set enp26s0f0 netns ns1       # [enp216s0f0] is the name of nic2
+    ip netns exec ns1 ifconfig enp26s0f0 1.1.1.8 up
+    ip netns exec ns1 ethtool -K enp26s0f0 tso on

+3.  Set up vm with virto device and using kernel virtio-net driver::
+
+    taskset -c 31 /home/qemu-install/qemu-4.2.1/bin/qemu-system-x86_64 -name us-vhost-vm1 \
+       -cpu host -enable-kvm -m 2048 -object memory-backend-file,id=mem,size=2048M,mem-path=/mnt/huge,share=on \

+       -vnc :10 -daemonize
+
+4. In vm, config the virtio-net device with ip and turn the kernel gro off::
+
+    ifconfig ens4 1.1.1.2 up  # [ens3] is the name of virtio-net
+    ethtool -L ens4 combined 2
+    ethtool -K ens4 gro off
+
+5. Start iperf test, run iperf server at vm side and iperf client at host side, check throughput in log can get better performance than case5::
+
+    Host side :  taskset -c 35 ip netns exec ns1 iperf -c 1.1.1.2 -i 1 -t 60 -m -P 2
+    VM side:     iperf -s

Hi, Yinan
I think we have remove the parameter of "--socket-mem 1024,1024  --legacy-mem" , why are you adding it back ?
