Hey Everybody, Thanks for the feedback. Yeah, we're pretty sure that the amount of memory we work with is atypical, and we're hitting something that isn't an issue for most DPDK users. To clarify, yes, we're using 1GB hugepages, and we set them up via hugepagesz and hugepages= in our kernel's gr

Hey Folks, Our DPDK application deals with very large in memory data structures, and can potentially use tens or even hundreds of gigabytes of hugepage memory. During the course of development, we've noticed that as the number of huge pages increases, the memory initialization time during EAL init
