What's the equivalent of Linux'smitigations=offOn this bad boy?
mitigations=off
Not possible. They straight up disable hyperthreading lmao.
>>100193505cuck license
think you have to recompile a custom kernel with those default disabled features on
>>100193519>>100193745Wasn't there an option available to disable them like two years ago?
>>100193519What's the benefit of hyper-threading anyway? In my experience it just skews(doubles) CPU time accounting. Great if you rent computers instances to the unsuspecting public.

>I add $(curl https://make-linux-fast-again.com) into my /etc/sysconfig/grub
for me its memtest=10 mitigations=auto nosmt=force
>>100193836lmfao, this can't be true. I doubt curl even runs in grub.
>>100193945gets run on grub-mkconfig, not during boot
>>100193945lmao, this faggot has never compiled their own kernel.
>>100194020I have compiled a kernel dozens of times. Not everybody needs to know how to use your söy bootloader.
and from what i can tell it just curl's "mitigations=off" which im still kind of dumbfounded the amount of sh|wget myscript.sh there is these days goto docker's official website they recommend running their fucking shell script absolutely unheard of a decade ago mocked even
>>100194201The "curl and run this shell script" retardation was originally by/for Macfags, then it somehow became normalized in Linux.

>>100194201cause get this, i could a site like that and might even work for a time, and now i have users sourcing a script include by a root user...
>>100194020what happens to the site when he dies?niggas looking pretty old

>>100193519>>100193761sysctl hw.smt=1 (need to update sysctl.conf to make it permanent)>>100193505Add softdep and noatime to your partitions in fstab, modify your limits in login.conf, preferrably use chromium over firefox and enable acceleration. Also, make a separate partition to use for disk caching your browser https://man.openbsd.org/mount_mfs.8
>>100194654>sysctl hw.smt=1 (need to update sysctl.conf to make it permanent)But this just enables hyperthreading, right? Is there something like this but for the mitigations?
>>100193801It's to hide memory latency on a core. The hyperthreads share an ALU but have separate registers, so if 1 thread has to wait for a memory access the other can take over executing and use the ALU. This is basically how GPUs work to hide memory latency but there's many more "hyperthreads" sharing an ALU
>>100193505>installed an OS focused on security to disable security featuresI don't get it.
https://isopenbsdsecu.re/mitigations/
>>100194674>Is there something like this but for the mitigationsNo, because, unlike Linux, OpenBSD is a full-fledged operating system and especially one that aims to achieve autistic levels of security (how valuable that is is an entirely separate topic). And it targets that holistically, from many different angles. The latter part of my post points to most of the useful things you can do to improve performance (which is what I assume you are after)(and those in some aspects are overriding security restrictions which the project believes should be the default). Of course, no matter what you do, it'll always be noticeably slower than almost any Linux configuration you would work with.
>>100194802I have an in-order CPU, and Linux always activates the mitigations anyways. Is there a way to know if OpenBSD is also being retarded?
>>100194869>Is there a way to know if OpenBSD is also being retardedWhen it comes to anything "security"-related you can safely assume with almost certainty that it is indeed retarded kekEither way, you can check(and modify) the sysctl values, though you'd need to look into the manpage what each one is for and which ones you may want to amend man.openbsd.org/sysctl.2What's the chip?
