Apple idati kuthana ndi vuto latsopano la ZombieLoad mu ma processor a Intel kumatha kuchepetsa magwiridwe antchito mpaka 40% nthawi zina. Zoonadi, chirichonse chidzadalira purosesa yeniyeni ndi zochitika zomwe zimagwiritsidwa ntchito, koma mulimonsemo izi zidzakhala zovuta kwambiri pakugwira ntchito kwadongosolo.
Poyamba, tiyeni tikukumbutseni kuti tsiku lina zidadziwika za chiopsezo china chopezeka mu ma processor ambiri a Intel. Imatchedwa ZombieLoad, ngakhale Intel mwiniwake amakonda kugwiritsa ntchito dzina losalowerera ndale Microarchitectural Data Sampling (MDS) kapena Microarchitectural Data Sampling. Takambirana kale mwatsatanetsatane za ndi kupezeka .
Tsopano Apple yatulutsa mawu ake okhudza MDS, chifukwa makompyuta ake onse a Mac amamangidwa pa tchipisi ta Intel, motero amatha kuwukiridwa. Kampaniyo idaperekanso njira yolimba, koma yothandiza, malinga ndi izo, njira yotetezera kompyuta yanu.
"Intel yapeza zovuta zomwe zimatchedwa microarchitectural data sampling (MDS) zomwe zimakhudza makompyuta apakompyuta ndi laputopu okhala ndi ma processor a Intel, kuphatikiza ma Mac onse amakono.
Pa nthawi yolemba izi, palibe zodziwika bwino zomwe zimakhudza makasitomala athu. Komabe, ogwiritsa ntchito omwe amakhulupirira kuti makompyuta awo ali pachiwopsezo chowonjezereka atha kugwiritsa ntchito pulogalamu ya Terminal kuti apangitse malangizo owonjezera a CPU ndikuletsa ukadaulo wa Hyper-Threading okha, womwe umapereka chitetezo chokwanira kuzinthu zachitetezo izi.
Njira iyi ikupezeka kwa macOS Mojave, High Sierra ndi Sierra. Koma zitha kukhudza kwambiri magwiridwe antchito a kompyuta yanu.
Kuyesa kochitidwa ndi Apple mu Meyi 2019 kunawonetsa kuchepa kwa magwiridwe antchito mpaka 40%. Kuyesa kunaphatikizapo ntchito zamitundu yambiri komanso ma benchmark omwe amapezeka pagulu. Mayeso amachitidwe adachitidwa pogwiritsa ntchito makompyuta a Mac. Zotsatira zenizeni zitha kusiyanasiyana kutengera mtundu, masinthidwe, momwe amagwiritsidwira ntchito ndi zina."
Dziwani kuti kampaniyo kuti kuletsa Hyper-Threading sikofunikira. Mukungoyenera kugwiritsa ntchito mapulogalamu otsimikiziridwa. M'malo mwake, Apple idasiyanso wogwiritsa ntchito kusankha: dzitetezeni kwathunthu ndikuchepetsa magwiridwe antchito, kapena kusiya zonse momwe zilili. Intel idawonanso kuti idayika kale zigamba zotsutsana ndi MDS m'mapurosesa ake achisanu ndi chitatu ndi chisanu ndi chinayi, komanso m'badwo wachiwiri wa Xeon-SP processors (Cascade Lake), kotero ogwiritsa ntchito tchipisi sayenera kudandaula za kusatetezeka kwatsopano. .
Koma kawirikawiri, zimakhala kuti kuti mutetezedwe kwathunthu ku ZombieLoad, muyenera kusintha kasinthidwe kachitidwe ndikugwiritsa ntchito purosesa yaposachedwa kwambiri, kapena kuletsa Hyper-Threading, potero kuchepetsa kwambiri machitidwe a dongosolo. Ngakhale omalizawo sangateteze ku ziwopsezo zina zomwe zimagwiritsa ntchito kuphedwa kongoyerekeza. Pali, komabe, njira ina - kugwiritsa ntchito dongosolo pa purosesa ya AMD. Koma pankhani ya makompyuta a Apple izi sizingatheke.
