Imemori egciniweyo yinkumbulo esetyenziswa nguLinux kugcino lwediski. Nangona kunjalo, oku akubalwa njengememori "esetyenzisiweyo", kuba iya kukhululwa xa izicelo ziyifuna. Ke akufuneki ube nexhala xa kusetyenziswa isixa esikhulu.
Yintoni i-cache kwiLinux?
Ngaphantsi kweLinux, iCache yePhepha ikhawulezisa ufikelelo oluninzi kwiifayile kugcino olungaguquguqukiyo. Oku kwenzeka ngenxa yokuba, xa iqala ukufunda ukusuka okanye ukubhala kwimidiya yedatha efana ne-hard drives, i-Linux ikwagcina idatha kwiindawo ezingasetyenziswanga zememori, ezisebenza njenge-cache.
Kutheni imemori yecache isetyenziswa kwiLinux?
I-Linux ihlala izama ukusebenzisa i-RAM ukukhawulezisa imisebenzi yedisk ngokusebenzisa imemori ekhoyo ye-buffers (imetadata yenkqubo yefayile) kunye ne-cache (amaphepha anomxholo wokwenyani weefayile okanye izixhobo zokubhloka). Oku kunceda inkqubo ukuba isebenze ngokukhawuleza kuba ulwazi lwedisk sele lukwinkumbulo egcina imisebenzi ye-I/O.
Yintoni i-cached memory?
Ugcino lwememori (oludla ngokubizwa ngokuba lugcino) bubuchule apho usetyenziso lwekhompyuter lugcina okwethutyana idatha kwinkumbulo engundoqo yekhompyuter (okt, imemori yofikelelo olungacwangciswanga, okanye i-RAM) ukuvumela ukufunyanwa kwakhona kwaloo datha.
