Benchmarking transparent versus 1GiB static huge page performance in Linux virtual machines

Benchmarking transparent versus 1GiB static huge page performance in Linux virtual machines

In this article, I examine the performance of two virtual machines (VMs) using huge pages in the Linux kernel. One VM is configured to use transparent huge pages (THP), which happens by default. The other is configured to use 1GiB static huge pages (SHP), which requires special configuration on the virtualization host and in the virtual machine definition.
