+1. Bind one port to igb_uio, then launch vhost by below command::
+
+    rm -rf vhost-net*
+    ./x86_64-native-linuxapp-gcc/app/testpmd -n 4 -l 2-4  --socket-mem 1024,1024 --legacy-mem \

+    >set fwd mac
+    >start
+
+3. Send packet with packet generator with different packet size,includes [64, 128, 256, 512, 1024, 1518], check the throughput with below command::
+
+    testpmd>show port stats all
+
+4. Repeat the test with dequeue-zero-copy=0, compare the performance gains or degradation. For small packet, we may expect ~20% performance drop, but for big packet, we expect ~20% performance gains.
