- Ukuphatha inqolobane efanele kanye nokwenza kahle kuthuthukisa ukusebenza kwesistimu.
- Ukunakekelwa okufanele kungavimbela izinkinga ezivamile ezihlobene nenqolobane.
Imemori ye-cache (noma isitoreji sesikhashana ) iyisici esibalulekile kunoma yiluphi uhlelo lwekhompyutha, esebenza njengebhuloho elisheshayo phakathi kwememori eyinhloko neprosesa. Nakuba ivame ukunganakwa, umthelela wayo ekusebenzeni kahle kwesistimu kanye nesivinini mkhulu kakhulu. Ukuba khona kwayo kusekelwe esimisweni sokuthi izinhlelo zekhompyutha zingafinyelela idatha ngokushesha uma igcinwa okwesikhashana ku-buffer eduze kweprosesa, esikhundleni sokuthembela kuphela kumemori eyinhloko ehamba kancane. Lesi sici sememori ye-cache siba yinzuzo ebalulekile yokusheshisa ukusebenza kwesistimu kanye nokuthuthukisa ukuphendula kwesikhathi sangempela.
Kulesi sihloko, sizodalula izimfihlakalo zenqolobane, sibonise ukuthi isebenza kanjani njengesisheshisi esithule sohlelo lwakho. Ngohambo oluningiliziwe, sizohlola ukwakheka kwayo, izinhlobo ezahlukene kanye namazinga enqolobane, nokuthi ukuphathwa kahle kwenqolobane kungathatha kanjani ukusebenza kwesistimu yekhompyutha kuyise ezingeni elilandelayo. Sizophinde sixoxe ngokuthi intuthuko yezobuchwepheshe iqhubeka kanjani nokuthuthukisa ukugcinwa kwesikhashana, okuvumela amasistimu ekhompiyutha ukuthi ahlangabezane ngokuphumelelayo nezinselele zenkathi yedijithali ehlala ishintsha.
Iyini inqolobane?
Imemori ye-cache uhlobo lwememori eguquguqukayo enikeza isitoreji esisheshayo seprosesa. Iyasiza ekunciphiseni isikhathi esithathwa yiprosesa ukufinyelela imemori eyinhloko (i-RAM). Kodwa ikwenza kanjani lokhu?
Isebenza kanjani i-Cache Memory
Inqolobane igcina okwesikhashana amakhophi eziyalezo nedatha esetshenziswa njalo, igwema isidingo sokufinyelela kumemori eyinhloko ehamba kancane.
Izinhlobo Zenkumbulo Yenqolobane
Kunezinhlobo ezahlukene zememori ye-cache; I-L1, i-L2 ne-L3, ngayinye inezici zayo nezinjongo ezithile.

Imibuzo ebuzwa njalo
1.- Kwenzekani uma inqolobane ihluleka?
Ukwehluleka Kusitoreji Sesikhashana kungabangela ukwehla okuphawulekayo ekusebenzeni kwesistimu ngoba i-CPU kuzodingeka ifinyelele kumemori eyinhloko kancane kancane isikhathi ngasinye. Ukwengeza, ingabangela amaphutha ezinhlelweni zokusebenza noma ohlelweni lokusebenza uma idatha eyonakele noma engalungile ifundwa noma ibhalwa kunqolobane. Kwezinye izimo ezimbi kakhulu, ukuphuthelwa kwenqolobane kungaholela ekulahlekeni kwedatha ebalulekile uma idatha ingalondolozwanga kumemori eyinhloko noma isitoreji sesibili.
2.- Ngingasibheka kanjani isimo senqolobane yami?
Amathuluzi ambalwa nemiyalo iyatholakala ukuze ikusize ugade futhi uhlole isimo senqolobane. Isibonelo, kumasistimu asekelwe ku-Windows, ungasebenzisa i-Performance Monitor noma amathuluzi ezinkampani zangaphandle njenge-CPU-Z. Kuzinhlelo ze-Linux, imiyalo efana free y vmstat, noma amathuluzi afana htop, inganikeza ulwazi olubalulekile. Kukhona futhi ukuxilonga kwezingxenyekazi zekhompuyutha ezithile ezingahlola isimo senqolobane futhi kutholwe izinkinga ezingaba khona.
3.- Kungenzeka yini ukwandisa usayizi wenqolobane?
Ukwandisa usayizi Wesitoreji Sesikhashana kuwumsebenzi oyinkimbinkimbi ongadinga ihadiwe eyengeziwe noma iphrosesa entsha enenqolobane enkulu. Lokhu kungenxa yokuthi inkumbulo yenqolobane ihlanganiswe kuphrosesa noma kubhodi lomama kwezinye izimo. Kungase futhi kube nezinketho ku-BIOS/UEFI ukulungisa izilungiselelo zenqolobane, nakuba lokhu kuvamile. Amanye amasistimu avumela ukucushwa kwenqolobane yediski, esebenzisa ingxenye ye-hard drive njenge-cache eyengeziwe, nakuba ingeke isheshe njengenqolobane ekuphrosesa.
4.- Ingabe ukulungiselelwa kwenqolobane kudinga ulwazi oluthuthukisiwe lobuchwepheshe?
Yize ezinye izici zokuthuthukisa inqolobane zingaba zobuchwepheshe futhi zidinga ulwazi oluthuthukisiwe, kunezenzo ezilula noma yimuphi umsebenzisi angazithatha ukuze alungiselele inqolobane. Isibonelo, ukugcina isistimu yokusebenza nezinhlelo zokusebenza kusesikhathini samanje, ukugwema ukusebenzisa izinhlelo zokusebenza eziningi ngesikhathi esisodwa, nokuqinisekisa ukuthi isistimu ine-RAM eyanele kungasiza ekunciphiseni ukuthembela kunqolobane futhi kuthuthukise ukusebenza.
5.- I-cache iyithinta kanjani impilo yesistimu yami?
Inqolobane ephethwe kahle futhi ethuthukisiwe inganweba impilo yesistimu yakho ngokunika amandla ukusebenza kahle nokunciphisa ukuguga kwezinye izingxenye ezifana nama-hard drive noma i-RAM. Ukwengeza, ukuphathwa kwe-cache okusebenzayo kungasiza ekugwemeni izingqinamba futhi kuthuthukise ukusebenza okuphelele, okungase kunciphise isidingo sokuthuthukisa ihadiwe njalo.
6.- Iluphi uhlobo lwenkumbulo yenqolobane olulungele uhlelo lwami?
Uhlobo olufanele lwe -cache yesistimu yakho luzoncika ezintweni eziningana, okuhlanganisa ukusetshenziswa kwayo okuhlosiwe, ukucushwa kwesistimu, kanye nehadiwe ekhona. Isibonelo, izinhlelo ezizinikele emisebenzini enzima njengokucubungula ihluzo noma ukuhlela ividiyo zingazuza kwi-cache enkulu noma ethuthukisiwe kakhulu. Kubalulekile futhi ukucabangela ukuhambisana phakathi kwe-cache ne-processor, kanye nesistimu yokusebenza. Ukubonisana nochwepheshe noma ukwenza ucwaningo olunzulu kungakusiza ukuthi unqume uhlobo lwe-cache olufanele kakhulu izidingo zakho.
Isiphetho
Inqolobane, ngaphandle kokungabaza, iyisisheshisi esithulile enhliziyweni yohlelo lwakho, okwenza ukusebenza okushesha nokusebenza kahle kwenzeke. Ngokwenza kahle nokunakekelwa okufanele, ungaqinisekisa ukuthi uhlelo lwakho lusebenza ngokugcwele. Yabelana ngalesi sihloko ukuze usize abanye baqonde futhi balungiselele inqolobane kumasistimu abo!
