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.
Ask yourself: do you really need a performance boost or are you just chasing the numbers to avoid a non-existant problem?
Yea
Everything is secure until it isn’t. I’d leave it on.
The short answer, as a ton of people already said in the comments of the video, is “hell no” it is not and it is most likely also not worth it. Back when the video came out I tested it (with unplugged network) on my system and the performance gain was ~1% which I’d consider well within the margin of error
Mines about 60% faster, ymmv
What workload makes that much of a difference?
Games on a 3rd gen i7
Which games?
Aren’t you the guy who runs one of the largest RuneScape private servers? Why tf are you disabling security measures
Isolated machine for emulating old consoles
…or you could opt for other ways to improve your PC performance. For instance, using equal values for both
scaling_max_freqandscaling_min_freqgives 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.
Eh…I see your point.
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.
It depends on how importent security is for that system and how devestating it would be if someone else got control over it and all accounts and devices connected to it.
Assuming there are sucessful exploits it would be like running everything as root and disabling all sandbox/isolation features from the kernel and browsers. I’d say you should not connect such a machine to the internet.
Link for the video?
As a general rule of thumb, I’ve been told that anything less than a 50% performance boost is hardly noticeable.
I’ve also heard (but ready to stand corrected) that mitigation costs only about 10% CPU (depending on the CPU).
I don’t get out of bed for a 10% performance boost.
99% of mitigations generally aren’t for vulnerabilities that affect day-to day users, so I’d say that you’ll probably be fine
This is exceptionally bad advice.
I like living on the edge
Then post your credit card number, expiry, and CVC
You ain’t gonna get much out of it, even if I do lol
Not important, until some day a virus is on Flathub, a user downloads a stupid appimage and they get in trouble
