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.
