Lub Chaw Ua Haujlwm Nruab Nrab (CPU) yog "lub hlwb" ntawm koj lub computer thiab ua cov haujlwm uas yuav tsum tau ua ntawm txhua daim ntawv thov uas koj tab tom khiav. Qhov ntawd suav nrog cov haujlwm nquag, ua haujlwm tom qab, thiab kev pabcuam kev ua haujlwm.
Koj tuaj yeem pom kev siv CPU hauv Kev Ua Haujlwm Saib Xyuas ntawm Mac (duab hauv qab). Tus Thawj Saib Xyuas Haujlwm ntawm Windows ua haujlwm tib yam.
CPU kev siv yog feem pua ntawm tag nrho CPU peev xwm koj siv nyob rau lub sijhawm twg los tau. Cov khoos phis tawj qub siv los muaj ib lub CPU uas tuaj yeem ua haujlwm tsuas yog ua haujlwm ib zaug xwb. Txawm li cas los xij, cov khoos phis tawj niaj hnub muaj CPUs nrog ntau "cores."Cov no yog cov processors nrog ntau lub processors sab hauv, txhua tus tuaj yeem ua haujlwm ntau yam haujlwm ib txhij.
CPU siv txhais li cas?
Thaum koj saib cov ntsiab lus hais txog kev siv CPU ntawm koj lub khoos phis tawj, koj yuav pom tus nqi feem pua uas sawv cev rau "feem pua kev siv." Nws yog npaum li cas ntawm koj tag nrho CPU lub zog ua haujlwm tam sim no tau siv.
Koj tseem yuav pom cov ntaub ntawv xws li CPU qhov kev ua haujlwm ceev tam sim no, tus lej ntawm cov txheej txheem thiab xov uas khiav, thiab ntau dua.
CPU feem pua siv tau tuaj yeem sib txawv heev nyob ntawm seb koj ua dab tsi nrog koj lub computer. Thaum lub khoos phis tawj ua ntej khau raj, ntau cov haujlwm thiab cov txheej txheem pib, thiab kev siv CPU yuav zoo li nyob ze rau 100% kom txog rau thaum lub khoos phis tawj tag nrho booted. Thaum koj ntaus ntawv lossis nyeem nplooj ntawv web thaum lub sijhawm ua haujlwm tsis tu ncua, kev siv CPU yuav nyob ntawm 1% txog 5%.
Txuag cov ntaub ntawv lossis tso tawm qhov program tshiab, thiab koj yuav pom kev siv CPU nce ntawm 50% mus rau 100% kom txog thaum ua tiav.
CPU siv ntau dhau yog dab tsi?
Yog tias kev siv CPU siab rau lub sijhawm luv, tsis muaj qhov zoo li kev siv siab dhau. Qhov ntawd yog vim 100% ntawm CPU yuav tsum tau ua haujlwm tshwj xeeb. Txawm li cas los xij, qhov kev siv siab feem ntau poob mus rau "ib txwm" qib.
Thaum koj siv CPU hauv Tus Thawj Saib Xyuas Haujlwm lossis Tus Saib Xyuas Kev Ua Haujlwm tseem siab dua 10% mus rau 30% rau lub sijhawm txuas ntxiv, nws tuaj yeem qhia tias koj muaj ntau daim ntawv thov ua haujlwm hauv keeb kwm yav dhau los txhua lub sijhawm. Cov ntawv thov uas yuav khiav hauv keeb kwm yav dhau los thiab nce koj qhov kev siv CPU suav nrog:
- Antivirus lossis anti-malware programs
- qhov kev pabcuam hloov tshiab Windows (yog tias nws tau teeb tsa kom hloov kho tau)
- software uas hloov kho nws tus kheej zoo li Adobe applications lossis Java
- server software zoo li iTunes lossis lub vev xaib hauv zos lossis FTP server
- Apps koj tau nruab uas kho koj lub computer tus neeg siv interface thiab yuav tsum tau khiav ntsiag to
- Kab mob ua haujlwm cov ntaub ntawv lossis cov txheej txheem
Koj tuaj yeem pom tag nrho cov txheej txheem nquag khiav hauv keeb kwm yav dhau hauv Tus Thawj Saib Xyuas Haujlwm lossis Tus Saib Xyuas Haujlwm. Hauv Windows, koj tuaj yeem pom dab tsi software launches tau los ntawm kev txheeb xyuas cov ntawv pib pib.
Koj tuaj yeem txo koj qhov kev siv CPU tag nrho los ntawm kev tshem tawm txhua yam hais saum toj no. Nws yooj yim npaum li kev txhim kho CPU tsawg dua kev tiv thaiv kab mob, tua cov software teeb tsa kom pib hloov tshiab, lossis tshem tawm software zoo li iTunes lossis FTP server.
Kev siv CPU zoo yog dab tsi?
Kev siv CPU li qub thaum koj tsis ua haujlwm software lossis thauj cov nplooj ntawv web yog nyob ib puag ncig 1% txog 5%. Cov haujlwm hauv qab no tuaj yeem tsim cov qib CPU hauv qab no. Tag nrho cov no suav hais tias yog "zoo" CPU siv ntev npaum li koj paub txog qhov ua rau nws.
- Siv ib txoj haujlwm uas muaj ntau yam xws li kev ua si sib tw: 10% txog 30%
- streaming video ntawm Netflix lossis YouTube: 5% txog 20%
- Kev xav tau kev ua si hauv computer: 50% txog 70%
- Booting koj lub khoos phis tawj lossis qhib qhov program tshiab: 80% txog 100%
Yog tias koj tsis ua dab tsi hauv koj lub computer lossis tsis ua haujlwm rau koj lub khoos phis tawj nrog ua qee yam hnyav, thiab koj tuaj yeem pom koj CPU nyob twj ywm siab dua 10%, koj yuav tsum tau teeb meem koj qhov teeb meem siv CPU.. Ua ntej, xyuas seb Windows puas ua haujlwm hloov tshiab. Tom qab ntawd, siv Task Manager lossis Activity Monitor los txheeb xyuas CPU kev siv los ntawm cov txheej txheem los taug qab cov kev pabcuam lossis qhov haujlwm twg yuav ua rau muaj teebmeem.
