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-songmuc...@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
