[dpdk-dev] Why IP_PIPELINE is faster than L2FWD

Hi all,

I tested default L2FWD and IP_PIPELINE (pass-through). The throughput of
IP_PIPELINE is higher immensely.

There are only two virtual NICs in KVM. The experiment is just moving
packet from vNIC0  to vNIC1. I think the function is so simple. Why L2FWD
is much slower?

How can I improve L2FWD, to make L2FWD faster?

Thanks!
