Ubuntu is now allowing users to disable security mitigations Intel has baked into its GPU components. People are claiming the setting provides up to a 20% boost in performance. I'm still trying to understand more about the mitigations, but they appear to involve defending against Spectre-based attacks. Is this wise? On the one hand, I'm not aware of a single Spectre-based attack in the wild. On the other hand, you're leaving yourself potentially exposed. Thoughts
