It's been a few years since Spectre and Meltdown were major news stories and since the mitigations were added for those and other exploits you've been able t...
Is it known how much faster a PC can get by disabling this? Could be useful with multiple Kernels, one for work without offline (rendering?) in the night and the other when going back online, with protections.
Not sure if that would be safe to do. Also what about Virtual Machines?
don't you run a kernel with the flags to disable those mitigations? The performance impact can be noticeable in some situations, so I tend to disable these mitigations and get a bit of improvement. Granted, I don't know how the performance impact is now, but I remember (maybe incorrectly) them decreasing the performance up to ~20% in some situations and depending on the mitigation. Maybe I read it on Phoronix or something, I can't recall
