Subject: [dpdk-dev] Why IP_PIPELINE is faster than L2FWD
Date: Thu, 22 Dec 2016 00:18:12 +0800 [thread overview]
Message-ID: <CAOwUCNs=c_5Ndb1+8zjJuhmA+i109XS5VjT00XvX-LpHP3GrWQ@mail.gmail.com> (raw)
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!
