Is It Worthwhile Running Intel Alder Lake With mitigations=off?
Over the past month of trying out Intel Alder Lake processors on Linux, one of the questions that has come up a few times but not readily disclosed is whether it's still worthwhile on this latest-generation process to boot with "mitigations=off" to disable CPU security mitigations to help squeeze out some otherwise lost performance. Here are some benchmarks to answer that questions.
