Shashi, You can’t really compare macswap with a full fledged host stack. As you delegate more work to vpp, you should expect a drop in throughput.
Also worth noting is that the stack sends/receives byte streams, not single packets and up to transport layer, it does make use of vectorization. The amount of bytes transferred per call depends on the size of the fifos and app buffers used. Depending on your hardware, the builtin echo client/server can push more than 10Gbps/connection. If you use more connections in parallel, you should be able to go over 20Gbps.
