Description

The memory page size of your system influences the overhead of virtual to physical memory translations, increasing your memory page size would reduce this overhead. HugePages is a feature that makes it possible for the operating system support memory pages larger than the default 4KB, assuming HW support. Hugepage support can deliver a significant improvement in memory access throughput, especially in memory intensive and database workloads.

This feature enables libvirt configure virtual machines to use hugepage backed memory.

This feature can be used Intel DPDK vSwitch and NFV workloads.
