Apple: Kugadzirisa ZombieLoad kusagadzikana kunogona kuderedza Mac kuita ne40%

Apple yakataura kuti kugadzirisa zvizere kutsva kweZombieLoad muIntel processors kunogona kuderedza kushanda kusvika ku40% mune dzimwe nguva. Ehe, zvese zvinoenderana neiyo chaiyo processor uye mamiriro ayo anoshandiswa, asi chero zvipi zvingave izvi zvichave zvakakoshesesa kurova kune system performance.

Kutanga, ngatikuyeuchidzei kuti rimwe zuva zvakazivikanwa nezve kumwe kusagadzikana kwakawanikwa mune akawanda Intel processors. Inonzi ZombieLoad, kunyangwe Intel pachayo inofarira kushandisa zita rakarerekera reMicroarchitectural Data Sampling (MDS) kana Microarchitectural Data Sampling. Takatotaura zvakadzama nezvazvo dambudziko pacharo uye iripo nzira dzokuzvigadzirisa.

Iye zvino Apple yakaburitsa chirevo chayo maererano neMDS, nekuti ese macomputer ayo eMac akavakirwa paIntel chips, saka anogona kurwiswa. Iyo kambani yakapawo imwe yakaoma, asi inoshanda, maererano nayo, nzira yekudzivirira komputa yako.

"Intel yakawana kusadzivirirwa kunonzi microarchitectural data sampling (MDS) iyo inobata desktop nemalaptop makomputa ane Intel processors, kusanganisira ese emazuvano Mac.

Panguva yekunyora uku, hapana zvinozivikanwa zviitiko zvinobata vatengi vedu. Nekudaro, vashandisi vanotenda komputa yavo iri panjodzi yakawedzera yekurwiswa vanogona kushandisa iyo Terminal application kugonesa yekuwedzera CPU kuraira uye kudzima Hyper-Threading tekinoroji ivo pachavo, iyo ichapa dziviriro yakakwana pazvinhu izvi zvekuchengetedza.

Iyi sarudzo inowanikwa macOS Mojave, High Sierra uye Sierra. Asi inogona kuve nekukanganisa kukuru pakuita kwekombuta yako.

Kuedzwa kwakaitwa neApple muna Chivabvu 2019 kwakaratidza kudonha kwekuita kunosvika makumi mana%. Kuedzwa kwaisanganisira mabasa akawanda ane shinda uye mabhenji anowanikwa pachena. Miedzo yekushanda yakaitwa uchishandisa yakasarudzwa Mac makomputa. Mhedzisiro chaiyo inogona kusiyana zvichienderana nemuenzaniso, kumisikidzwa, mamiriro ekushandiswa nezvimwe zvinhu."

Cherechedza kuti kambani Intel akadaro kuti kudzima Hyper-Threading hazvidiwi. Iwe unongoda kushandisa software yakasimbiswa. Chaizvoizvo, Apple yakasiyawo mushandisi sarudzo: kuzvidzivirira zvachose uye kuderedza kuita, kana kusiya zvese sezvazviri. Intel yakacherekedzawo kuti yakatoshandisa zvigamba zvehardware kurwisa MDS mune yayo yechisere neyepfumbamwe chizvarwa processors, pamwe nechizvarwa chechipiri Xeon-SP processors (Cascade Lake), saka vashandisi veaya machipisi havafanirwe kunetseka nezve hutsva hutsva. .

Asi kazhinji, zvinoitika kuti kuti uve nechokwadi chekuchengetedzwa kwakazara kubva kuZombieLoad, unofanirwa kugadzirisa masisitimu ehurongwa uye kushandisa imwe ichangoburwa processor mairi, kana kudzima Hyper-Threading, nekudaro ichideredza zvakanyanya mashandiro ehurongwa. Kunyangwe iyo yekupedzisira isingadziviriri kubva kune dzimwe kutyisidzira dzinoshandisa fungidziro yekuraira kuuraya. Pane, zvisinei, imwe sarudzo - kushandisa system pane AMD processor. Asi panyaya yemakomputa eApple izvi hazvigoneke.
