Over the past month we have been quite impressed by the performance of the EPYC 7003 series Milan processors when looking at the top-tier parts, but how does Zen 3 do for lower-tier server CPUs? Recently we were supplied with two EPYC 72F3 processors from AMD for these 8-core high performance SKUs. In our initial look at the EPYC 72F3 Linux performance is seeing how they compare to the similar previous-generation EPYC 7F32 processor.

Linux 5.11 brought mainline support for Intel Software Guard Extensions (SGX) after a lengthy mainlining process. Building off that SGX enclaves support in the mainline kernel more recently has been support for SGX with KVM virtualization and now for mainline Linux 5.13 that guest-side support is landing for KVM guests...
