Ubuntu Server 20.04 CPU Security Mitigation Performance Impact

Fri, 04/17/2020 - 03:00
Earlier this week I published new benchmarks looking at the desktop CPU security mitigation impact with Ubuntu 20.04. Here are similar tests done in looking at the server mitigation impact with the near-final Ubuntu 20.04 LTS while testing server workloads on Intel Xeon and AMD EPYC server platforms. Like the desktop tests, the mitigation impact with the out-of-the-box protections against Spectre, Meltdown, and friends is being compared to booting the same Ubuntu 20.04 release with "mitigations=off" for run-time disabling of the relevant mitigations on each platform.
