Hi all,
FYI
The incoming kernel mm patch will save ~1.6% Memory for 1G hugepage
and ~1.2% for 2M hugepage, which is a good news for DPDK.
https://lore.kernel.org/linux-doc/20210510030027.56044-5-songmuchun@bytedance.com/
if you run a server with 1TB Dram, you can save ~16G.
this patches has been tested on bytedance/huawei/aws platform.
it looks very promising(might be merged into next version kernel rc)
Regards
Liang
