--- Comment #1 from Andrew Pinski <pinskia at gcc dot gnu.org> ---
First off the performance is difference is die to micro-arch issues with
unaligned stores of 256 bits. 

Also iirc rte_mov128blocks is tuned at copying blocks which are aligned at
least to 32 bytes wide. But you are better asking the dpdk forum why they don't
just use memcpy here.
