The title used here (“Your next OS X update will reduce CPU performance by up to 40%”) is an inaccurate summary of the support article.
Per the article, the update won’t affect CPU performance. It will apply Apple’s recommended mitigations for the recent batch of vulnerabilities for most workloads. But for users with higher risk workloads or who are planning to execute untrusted code, they’re adding a configuration option which would enable more stringent mitigation’s. Those mitigations have the 40% perf hit.
