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?

    The system will be secure for personal use as before.

    I wouldn’t be so sure of that. CPU side channels allow data to be leaked across security contexts. For example, from a user process to sandboxed JavaScript in a browser, from kernel space to user space, or from one containerized process to another. This is a problem even on a single user system without any VMs.

  • 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
