One of the real-world workloads most impacted by the SEV-SNP overhead comes down to database servers.
Running various database servers was at 85~90% the performance of the AMD EPYC Turin virtual machine without the SEV-SNP protections.
👁 Memcached benchmark with settings of Set To Get Ratio: 1:10. 26.04 Devel: Non-CVM was the fastest.

At least with the AMD EPYC 9005 series being as fast as they are relative to the competition, the 10~15% hit to database workloads still allows for competitive performance relative to other CPUs while maximizing data security.
