Don't forget to disable all "spectre and friends" mitigations in your linux kernel, and some workloads will become much faster. Can you do the same on the wind

Don't forget to disable all "spectre and friends" mitigations in your linux kernel, and some workloads will become much faster.
Can you do the same on the windows kernel or apple kernels?
- dyauspitr 3mo agoInteresting, did not know you could do that but it does make sense. Make sure it’s air gapped.
- xyzsparetimexyz 3mo agohttps://wiki.archlinux.org/title/Improving_performance#Turn_off_CPU_exploit_mitigations https://wiki.archlinux.org/title/Improving_performance#Turn_... Arch wiki says its okay.
- xyzsparetimexyz 3mo agoOnly really on CPUs with the vulnerability
- sylware 3mo agomitigations do slow all CPUs, even those without the vulns. You need alternative linux kernels with their modules.
- tredre3 3mo agoYes you can do the same on Windows. https://www.grc.com/inspectre.htm https://www.grc.com/inspectre.htm
- sylware 3mo agoYou have to recompile the kernel to remove some mitigations about "indirect branching", namely you must have alternative windows kernels. Do you have those windows kernels?
