Highlights We were able to disable some Spectre / Meltdown JIT mitigations! Nightly-only for now. These were mitigations we deployed years ago to protect users against various timing …
@op how did you post this in the future? It’s messing with the sorting algorithm when you are displaying “All” posts.
I just added a link to the firefox magazine using Fedia’s + button. Should I be doing something different? Maybe my system time is off?
I remember browsing the day Spectre and Meltdown were made public… News articles about how everybody’s accounts were about to be hacked, enthusiasts claiming mitigations would make Intel go bankrupt and that all CPUs would lose 80% of their performance… Fun times.
To be fair, given how many high-profile data breaches there have been since, and the fact that CPU performance was significantly affected, and how much Intel has struggled to remain competitive, I’m not sure we were all that far off from any exaggerations.
in linux you can switch kernel mitigations on and off and it’s barely noticable, even when gaming.
Sure, but that’s after years of researching and tweaking the mitigation, and doesn’t cover other OSes. I certainly agree that some folks made it sound a lot more dire than it ever was, though.
