Ob peb ntawm cov lus nquag nug thaum txhim kho Linux - qhov loj npaum li cas yuav tsum sib faib sib faib thiab nws xav tau txhua? Yav dhau los, nws tau pom zoo ua qhov sib faib sib faib ob npaug ntawm tus nqi ntawm RAM, tab sis tam sim no, thaum cov nyiaj ntawm RAM hauv lub computer tuaj yeem ncav cuag 128 gigabytes, txoj cai no tsis tas li siv, vim tias feem ntau ib qho sib faib sib faib yuav nkim qhov chaw seem dawb. nyob rau lub hard disk. …
Dab tsi yog kev sib faib ib qho pauv thiab nws yog dab tsi
Thaum cov kev pab cuam pib, nws cov cai thiab qee cov ntaub ntawv yog loaded rau hauv RAM (Random Access Memory). Yog tias ib lossis ntau cov kev khiav haujlwm yuav tsum muaj RAM tsawg dua li ntsia ntawm lub khoos phis tawm, ces lawv yuav ua haujlwm txuas ntxiv mus. Tab sis, yog tias muaj qhov chaw tsawg dua nyob hauv RAM tshaj qhov kev zov me nyuam xav kom thauj nws cov ntaub ntawv, tom qab ntawd nws yuav muab qhov yuam kev thiab nres ua haujlwm.
Nyob rau cov sijhawm tam sim no, Linux pib siv qhov sib pauv-muab faib rau lub hard disk li RAM, "nce" nws cov ntim muaj - nws txav cov ntaub ntawv tsis siv los ntawm RAM rau nws, tso tawm hauv thaj chaw rau qhov tshiab.
Nws yuav zoo li, vim li cas tom qab ntawd koj puas xav tau RAM kim ntawm txhua lub sijhawm, yog tias rau tib cov nyiaj koj tuaj yeem yuav lub zog loj dua thiab siv txhua yam raws li kev sib faib? Nws yog txhua yam txog kev nrawm. Kev nkag mus rau cov ntaub ntawv hauv RAM yog kwv yees li ib txhiab txhiab lub sij hawm sai dua ntawm lub hard drive (cov ntaub ntawv muaj tseeb sib txawv ntawm qhov system mus rau system). Kev ua haujlwm tib yam nrog kev nkag mus rau cov ntaub ntawv hauv RAM thiab sib faib sib faib, uas yuav siv sijhawm ib ob hauv thawj kis, yuav siv sij hawm ntau lub sijhawm hauv ob.
Yog li, txoj kev sib faib nrawm tsis haum rau kev siv tas mus li thaum nkag mus siv lub cim xeeb, tab sis nws tuaj yeem pab tau ntau thaum lub sijhawm siab, tiv thaiv cov kev zov me nyuam kom khov thiab nres.
Yog li ntau npaum li cas qhov chaw koj yuav tsum tau faib rau qhov sib faib sib faib?
Nws tsis tuaj yeem txiav txim siab cov lus teb rau lo lus nug no, vim nws nyob ntawm kev teeb tsa tshwj xeeb ntawm lub system thiab thaj tsam ntawm cov haujlwm uas nws daws, tab sis muaj cov lus qhia yooj yim:
- yog hais tias tus nqi ntawm lub RAM tsawg dua 2 gigabytes, ces cov sib puav yuav tsum muaj tsawg kawg yog ob zaug
- yog hais tias tus nqi ntawm RAM ntau dua 2 gigabytes, ces qhov loj ntawm kev sib faib yuav tsum muaj qhov sib luag rau RAM * 2 + 2GB
- yog hais tias tus nqi ntawm lub RAM ntau tshaj 4 gigabytes, ces qhov loj ntawm kev sib faib yuav tsum muaj qhov sib npaug 20% ntawm qhov loj ntawm RAM
