Imemori Yokucindezela ingathuthukisa ukusebenza kwe-Mac yakho
Ngokukhululwa kwe- OS X Mavericks , i-Apple ishintshe ukuthi imemori iphethwe kanjani kwi-Mac. Ngokungezwa kokucindezeleka kwememori, i-Mac yakho manje ingenza okuningi ngokukhumbula okungenani ngenkathi igcina noma ikhula ukusebenza. Kuzinguqulo ezindala ze-OS X, ukusetshenziswa komemori kwakhiwe eduze nesistimu yokuphatha imemori ejwayelekile. Izinhlelo zokusebenza zicele ukwabiwa kwe-RAM, uhlelo lugcwalise isicelo, futhi izinhlelo zokusebenza zibuyisele i-RAM uma zingasadingeki.
I-OS inakekele imisebenzi eminingi engcolile yokugcina ithrekhi yokuthi i-RAM yayitholakali nokuthi ubani oyisebenzisayo. I-OS iphinde yazi ukuthi yini okufanele yenze uma inani le-RAM lidinga ayitholakali. Leyo ngxenye yokugcina yayibaluleke kakhulu ngoba kungase kube nemiphumela emibi ekusebenzeni kwe-Mac njengoba uhlelo luzama ukusebenzisa i- RAM yangempela (isikhala sokutshintsha ku-SSD noma i-hard drive).
I-Apple inikeze ngisho nethuluzi elihle kakhulu, umsebenzi we- Activity Monitor , ukuthi phakathi kwezinye izinto, ungabheka ukuthi i-RAM ye-Mac isetshenziswa kanjani. Ngenkathi umsebenzi we-Activity okwamanje usatholakala, amandla akhe okuqapha imemori ayenze ushintsho olukhulu, olulinganisa indlela i-Mac manje ekwazi ngayo ukusebenzisa i-RAM ngokusebenzisa imemori ecindezelekile.
I-Memory Compress
Imemori ecindezelekile akuyona into entsha noma i-Apple kuphela. Izinhlelo zekhompuyutha ziye zasebenzisa izinhlobo ezihlukahlukene zokucindezela inkumbulo isikhathi eside. Uma usebenzisa ama-Macs phakathi nama-80s nasekuqaleni kweminyaka engu-90, ungase ukhumbule imikhiqizo enjenge-RAM Doubler esuka ku-Connectix, eyayiqinisa idatha egcinwe ku-RAM, ngokwandisa ngokuphumelelayo inani lemali yamahhala etholakalayo ku-Mac. Ngikhumbula ngibona isithonjana se-RAM Doubler sibonakala njengoba i-Mac Plus yami iqalile. Ngikholelwa, i-Mac Plus, eyayine-4 MB kuphela ye-RAM, idinga lonke usizo i-RAM Doubler engayinika lona.
Izinsiza zememori ezicindezelekile azizange zithandeke njengoba abenzi bekhompyutha nabathuthukisi be-OS badala izinhlelo zokuphatha imemori ezingcono. Ngesikhathi esifanayo, izindleko zememori zahla. Esinye isici esenza ukuba inkumbulo yokucindezela inkumbulo ilahlekelwe ukuthandwa kwabo yinkinga yokusebenza. Ukubumbana kwememori yezintambo kwathatha amandla amakhulu okucubungula amandla. Lokhu kusho ukuthi ngenkathi bekuvumela ukuba wenze okuningi nge-RAM encane engokwenyama, babejwayele ukugubha phansi ikhompyutha yakho uma kudingeka ukucindezela noma ukukhipha imemori.
Ukuncintisana kwememori kwenza ukubuyela emuva, ngokuyinhloko ngenxa yokufika kwama-processor amaningi amaningi angabizi. Uma imizila esetshenziselwa ukucindezela imemori ingaxoshwa kwenye yezinhlamvu eziningi zokucubungula, cishe ngeke uqaphele noma yikuphi ukusebenza okusebenza lapho imemori idinga ukucindezelwa noma ukucindezelwa. Ngokumane kuba umsebenzi wangemuva.
Indlela I-Memory Compressed isebenza ngayo kwi-Mac
Ukuncintisana kwememori ku-Mac kuklanyelwe ukwandisa ukusebenza kwe-OS nokusebenza ngokuvumela ukuphathwa okungcono kwezinsiza ze-RAM nokuvimbela noma ukunciphisa kakhulu ukusetshenziswa kwememori ebonakalayo, okuyi-paging yedatha kuya kwi-Mac's drive.
Nge- OS X Mavericks (noma kamuva), i-OS ibheka imemori engasebenzi, okuyinto imemori engakayisebenzisi okwamanje kodwa isamba idatha ezosetshenziswa uhlelo lokusebenza. Le nkumbulo engasebenzi iphoqa idatha ukuthi ibambe, ngakho idatha ithatha imemori encane. Imemori engenakwenzeka ingaba izinhlelo zokusebenza ezingemuva futhi zingasetshenziswa. Isibonelo singaba iprosesa yezwi evulekile kodwa engasebenzi ngoba uthatha ikhefu futhi ufunda ngememori ecindezelekile (ngendlela, sibonga ngokuyeka nokufunda lesi sihloko). Ngesikhathi usuxhumane newebhu, i-OS icindezela inkumbulo yeprosesa yegama, ikhulula i-RAM ukuze isebenziswe ezinye izinhlelo zokusebenza, njenge-Flash player oyisebenzisayo ukubuka ibhayisikobho kuwebhu.
Inqubo yokucindezela ayisebenzi ngaso sonke isikhathi. Esikhundleni salokho, i-OS ihlola ukuqinisekisa ukuthi kungakanani isikhala samahhala esitholakalayo ku- RAM . Uma kunomthamo omkhulu wememori yamahhala, akukho ukucindezelwa okwenziwa, ngisho noma kunememori eminingi engasebenzi.
Njengememori yamahhala isetshenziselwa phezulu, i-OS iqala ukucinga imemori engasebenzi ukucindezela. Ukucindezela kuqala ngedatha endala kakhulu esetshenziswe kwimemori futhi isebenza phambili ukuze kuqinisekiswe ukuthi kunememori ekhululekile etholakalayo. Lapho idatha endaweni ephoqelelwe ye-RAM idingeka, i-OS idonsa idatha ngendiza iphinde itholakale kuhlelo lokusebenza oluyicela. Ngenxa yokuthi imizila yokucindezela nokucindezela iqhutshwa ngesikhathi esifanayo kwenye yezinhlamvu zokucubungula , awunakwenzeka ukubhekana nokulahlekelwa ukusebenza ngenkathi kwenzeka ukucindezeleka / ukucindezeleka.
Yiqiniso, kunemingcele kulokho ukucindezela okungaphumelela. Ngesinye isikhathi, uma uqhubeka ukuqala izinhlelo zokusebenza noma ukusebenzisa izinhlelo zokusebenza ezikhumbuza imemori ezihamba nge-RAM, i-Mac yakho ngeke ibe nesikhala esanele samahhala. Njengasekuqaleni, i-OS izoqala ukushintshanisa idatha ye-RAM engasebenzi emotweni yakho ye-Mac. Kodwa ngokucindezela inkumbulo, lokhu kungenzeka kube yinto engavamile kakhulu kubasebenzisi abaningi.
Ngisho noma ngabe i-OS iphetha ukuthi kufanele ishintshe imemori ku-drive yakho, uhlelo lokuphatha imemori lwe-OS X lusebenzisa inkumbulo engasebenzi ekubhala idatha ecindezelekile kumagceke okuhamba okude okugcwele, ukwandisa ukusebenza nokunciphisa ukugqoka kuma- SSD .
Ukuqapha umsebenzi nokucindezelwa kwememori
Ungakwazi ukuqapha ukuthi imemori icindezeleke kangakanani ngokusebenzisa ithebhu yeMemori ku-Activity Monitor. Imibukiso eminingi yezinkumbulo ezicindezelweyo egrafini ye-Memory Pressure, ekhombisa ukuthi i-OS ihileleka kangakanani ekucindezeleni idatha ye-RAM. Igrafu izophendukela kusuka eluhlaza (ukucindezelwa okuncane) ibe yikhuphu (ukucindezela okukhulu), futhi ekugcineni ibe obomvu, uma kungekho isikhala esanele se-RAM futhi imemori kufanele ihanjiswe ku-drive.
Ngakho-ke, uma uqaphele ukuthi i-Mac yakho ibonakala ibhekene nokunciphisa okungaphezulu ekusebenzeni kwayo kusukela ufake i-Mavericks, kungenzeka ukuthi ngenxa yentuthuko yokuphathwa kwememori nokubuyiswa kwememori.
