Evaluating The Performance Cost To AMD SEV-SNP On EPYC 9005 VMs

Phoronix - Fri, 02/13/2026 - 23:17
AMD Secure Encrypted Virtualization with Secure Nested Paging (SEV-SNP) provides memory encryption and integrity protections that can be especially useful in modern cloud computing. Typically a 2~10% performance overhead is reported when engaging AMD SEV-SNP for these hardware-backed security protections. In this article is an extensive look at the current AMD SEV-SNP performance impact for confidential computing on EPYC 9005 "Turin" servers. The current Ubuntu 24.04 LTS was tested as well as an Ubuntu 26.04 development snapshot in evaluating the latest optimizations and what is on the horizon this year for AMD EPYC Linux server performance.
