Hi,all,

         I have noticed that there is ¨Clegacy-mem option in dpdk init. But it¡¯s not a default choice.
In my understanding, hugepage can help decrease cpu cache miss and It affects performance a lot.
So I wonder that is legacy-mem mode perform worse than default mode£¿ Why not use legacy-mem mode as a default way to use hugepages?

Any help will be greatly appreciated
