ZombieLoad Mitigation Costs For Intel Haswell Xeon, Plus Overall Mitigation Impact

With tests over the past week following the disclosure of the Microarchitectural Data Sampling (MDS) vulnerabilities also known as “Zombieload”, we’ve looked at the MDS mitigation costs (and now the overall Spectre/Meltdown/L1TF/MDS impact) for desktop CPUs, servers, and some laptop hardware. I’ve also begun doing some tests on older hardware, such as some Phoronix readers curious how well aging Intel Haswell CPUs are affected…
