Is this a joke? Disabling mitigation to speed up your computer seems like a not good idea..
- junon 4y agoWhat's your threat model?
- cedilla 4y agoNot op, but probably a common reasoning: At home, I don't do threat models or risk assessments. I also don't care that much about 5 to 15% increase in benchmarks, I just hope that the OS vendor makes sensible decisions in regards to safety and performance. At work, I do care about small increases but I would never just copy some random kernel options found on an otherwise empty web site. Cargo culting useless or harmful options is a very tangible threat.
- junon 4y agoThe website explains each of them, no? Also, there are ways to investigate them...
- throwaway3neu94 4y agoThe website actually started as a sort of joke by someone in the kernel community. Then it stuck around. For example, I found it useful professionally. We're releasing a new hardware model. We're doing some in-depth performance tuning/evaluation. To understand our performance characteristics, I needed us to break down the performance change into improvement due to new hardware and reduction due to new mitigations. Linking this page in the Jira issue was the fastest way to get the point across what we needed to look into. It is not, at all, something I would ever recommend to lay people, or use in the actual shipping product.
