It's great to have guides like this, but there are a lot of recommendations in here, and I don't understand the implications of all of them, individually or together.
The author seems opposed to disabling security mitigations for performance reasons, but what are the trade-offs? What if you use your workstation for 3D rendering or machine learning, and you really do want to maximize the performance of your hardware?
- KingMachiavelli 4y agoMost of the options don't have much or any performance impact. The few that do e.g. the spectre/meltdown related ones provide improve security far more than they impact performance on a recent-year CPU. If these security options make or break your ability to do certain kinds of work - then you'd probably benefit most from using a more modern and faster CPU. If anything some of these options are more likely to break the occasional application completely e.g. some applications use user-namespaces.
