Do you think it is safe and secure to disable Mitigation in Fedora for the sake of performance?
I've seen a video from CTT demonstrating the <10 performance boosts by simply off the mitigation. The system will be secure for personal use as before.
...or you could opt for other ways to improve your PC performance. For instance, using equal values for both scaling_max_freq and scaling_min_freq gives you a quite considerable performance boost at the expense of (almost) nothing.
Well, you lose a lot of power efficiency, this would be massively detrimental to many peoples experiences if you do this on anything battery powered like a laptop.
And does this still work with modern cpufreq schedulers like amd-pstate and the Intel equivalent? IIRC I couldn't simply set frequencies or select the userspace scheduler on 10th gen Intel and frequencies don't seem to be honoured by AMD pstate drivers on Zen4.
