"Linus Torvalds: After big Linux performance hit, Spectre v2 patchneeds curbs"
"Linus Torvalds: After big Linux performance hit, Spectre v2 patch needs
curbs" https://www.zdnet.com/article/linus-...h-needs-curbs/ "Patch is causing as much as a 50 percent drop in performance in some Linux workloads." Well, that sucks. Reminds one of the good intentions rule, "The road to Hell is paved with Good Intentions". Lynn |

(what has gossip about Linux to do with Windows) I can see possibly his intent to say that Linux has it's issues along with Windows 10. It would have been better if he had eluded to that, but....

Mitigating Spectre is not something you normally need to do [unless you host VMs from multiple customers, or even shared hosting for a single VM, and things of that nature]. Linux is unlike Win-10-nic, which TAKES AWAY end-user control whenever possible! Instead, you can compile options in/out or just configure them the way you want them to with system variables. -- (aka 'Bombastic Bob' in case you wondered) 'Feeling with my fingers, and thinking with my brain' - me 'your story is so touching, but it sounds just like a lie' "Straighten up and fly right" |

With Microsoft, you can check your patch status. There are a few third party tools https://www.howtogeek.com/338801/how...n-and-spectre/ https://www.grc.com/inspectre.htm https://www.ashampoo.com/en/usd/pin/...wn-cpu-checker Microsoft itself provides a Powershell script, which isn't as nice. The Intel firmware update is optional with Microsoft. It's available as a separate download if you want it. This gives some control over whether you want that level of security or not. You can use the above tools, to check what has or hasn't been patched yet. Paul |
