> Subject: [dpdk-dev] [PATCH 0/2] L3FWD sample optimisation
>
> With latest HW and optimised RX/TX path there is a huge gap between
> tespmd iofwd and l3fwd performance results.
> So there is an attempt to optimise l3fwd LPM code path and reduce the gap:
> - Instead of processing each input packet up to completion -
> divide packet processing into several stages and perform
> stage by stage for the whole burst.
> - Unroll things by the factor of 4 whenever possible.
> - Use SSE instincts for some operations (bswap, replace MAC addresses, etc).
> - Avoid TX packet buffering whenever possible.
> - Move some checks from RX/TX into setup phase.
