Lub khoos phis tawm ntawm Windows 7 tau qhib qhov kev ua haujlwm ntawm lub thev naus laus zis tshwj xeeb hu ua SuperFetch. Qhov no thev naus laus zis yog dab tsi, thiab nws ua haujlwm li cas, tsis yog rau txhua tus paub. Tab sis yog tias koj nco ntsoov lub Prefetcher technology dhau los hauv Windows Vista, ces txhua yam tam sim ntawd poob rau hauv qhov chaw.
Kev tsim kho ntawm fab thev naus laus zis tshuab tsis sawv ntsug. Lub Windows 7 operating system ua rau nws ua tau los siv cov cim SuperFetch tshwj xeeb (nws muaj npe raws li cov txheej txheem sysmain hauv tus thawj tswj hwm). Txhawm rau kom nkag siab lub ntsiab lus thiab nkag siab cov haujlwm ntawm cov kev pabcuam no, koj yuav tsum nco qab lwm qhov tshwj xeeb Prefetcher thev naus laus zis hauv Windows Vista. Thaum twg cov programme raug tso tawm, nws cov ntaub ntawv teeb tsa thiab cov khoom siv tau pib nyeem los ntawm lub hard disk, thiab tsuas yog tom qab ntawd lawv tau ntsaws rau hauv RAM hauv tus tswv tsev hom. Thaum cov ntawv thov tawm los ntawm kev rov qhib nws, tib txoj kev yuav ua. Txhawm rau kom nkag mus sai rau cov kev pabcuam thiab, vim li ntawd, ua kom zoo ntawm kev ua haujlwm ntawm cov txheej txheem system, SuperFetch technology tau tsim thiab siv.
Ntse SuperFetch System: Cov Lus Qhia dav dav
Nrog kev pabcuam ntawm cov thev naus laus zis thev naus laus zis, cov kev kawm nrov tshaj plaws uas siv los ntawm tus neeg siv tau taug qab thiab tom qab ntawd muab tso rau hauv RAM rau kev nrhiav ceev. Yog li, qhov kev tshaj tawm ntawm qhov no lossis qhov haujlwm ntawd tau nrawm dua vim tias cov ntaub ntawv muaj nyob hauv RAM, uas yog vim li cas lub sijhawm ntxiv tsis siv los nyeem nws los ntawm lub hard drive. Yog tias koj saib keeb kwm ntawm kev tsim lub thev naus laus zis, tom qab ntawd nws tau thov thaum xub thawj nyob rau hauv lub qhov rais xp, thiab tom qab ntawd nws tau txuas ntxiv hauv Vista version thiab raug hu ua Prefetcher. Nws txoj haujlwm yog txhawm rau ua kom zoo dua ntawm kev thauj khoom ntawm cov system Cheebtsam thiab cov qauv ntawm cov ntawv thov ua ntej pib ncaj qha.
Cov thev naus laus zis yog li ntawd hu ua "Prefetch" lossis prefetcher (superprefetch). Cov kev pab no muaj teeb meem tseem ceeb. Nws tau tso cai thauj khoom tsawg tsawg ntawm cov kev pab cuam rau hauv RAM, thiab thaum ib daim ntawv thov tsis kam siv ntau zaus, nws cov ntaub ntawv tau tawm mus rau lub hard drive hauv cov ntaub ntawv paging. Tab sis tom qab ntawd, zoo meej tau hla loj hloov.
Tom qab kev txhim kho tseem ceeb, thev naus laus zis ua SuperFetch (txhais cov lus tseeb - superfetch). Tam sim no qhov kev pabcuam tau koom nrog cov neeg siv kev ua ub no, tsim cov phiaj xwm tshwj xeeb thiab txuag kev teeb tsa ntawm cov programmes siv. Yog tias vim qee yam kev thov daim ntawv tam sim ntawd ya tawm ntawm RAM, SuperFetch ua qhov kev soj ntsuam zoo tshaj plaws ntawm kev tshem tawm thiab, tom qab ua tiav ntawm cov txheej txheem lub luag haujlwm tsis xa khoom, rov qab ua tiav qhov kev pabcuam yav dhau los rau hauv RAM. Lub luag haujlwm tseem ceeb ntawm kev pab cuam yog kom nce lub xaib ntawm daim ntawv thov ceev thiab kom muaj kev ruaj khov ntawm cov txheej txheem kev ua haujlwm, uas ua rau muaj kev cuam tshuam nrog qhov nrawm rau qhov haujlwm.
Cov chaw muab kev pabcuam thiab kev tswj hwm
Txhawm rau kom tau txais cov kev pabcuam no, nws yog qhov zoo uas siv kev sau npe. Nyob rau hauv Dlaim menu (Win + R), lub regedit command hu rau tus editor. Hauv seem txheej txheem, siv HKLM ceg, koj yuav tsum nrhiav phau PrefetchParameters. Peb xav tau ob tus yuam sij EnablePrefetcher thiab EnableSuperFetch. Yog tias tsis muaj tus yuam sij EnableSuperFetch, ces nws yuav tsum tau tsim (DWORD parameter) thiab muab lub npe kom tsim nyog. Txog kev yooj yim, koj tuaj yeem nkag mus rau plaub qhov tseem ceeb rau txhua tus yuam sij:
- 0 - tiav kev kaw;
- 1 - kev ua kom tau zoo ntawm cov kev pab cuam tsuas;
- 2 - kev ua haujlwm tau zoo ntawm tsuas yog cov pib ua haujlwm;
- 3 - kev sib npaug nrawm ntawm daim ntawv thov thiab cov tshuab.
Kev siv cov kev pab.msc hais kom ua, uas qhib lub chaw qhib rau kev pabcuam thiab cov txheej txheem ua haujlwm, yog lwm txoj hauv kev los tswj cov chaw pabcuam. Hauv qhov no, koj yuav tsum nrhiav SuperFetch thiab qhib cov kev pabcuam cov khoom nrog ob npaug nias. Tom qab ntawd koj yuav tsum teeb tsa qhov yuav tsum tau muaj los ntawm daim ntawv teev cia hauv qab ntawm hom pib.
Qhov tsis zoo ntawm qhov kev pabcuam SuperFetch
Tab sis kuj tseem muaj qhov tsis zoo nyob rau qhov kev pabcuam no. Tsis ncaw kuj muaj cov teeb meem cuam tshuam nrog nws. Nrog kev txiav txim siab kom zoo ntawm qhov teeb meem no, koj tuaj yeem mus rau qhov xaus tias cov teeb meem uas tshwm sim thaum ua haujlwm nrog lub khoos phis tawm tsis yog qhov txhaum tsis yog los ntawm SuperFetch kev pabcuam. Ntawd yog, yog tias peb tham txog qhov ua tsis tiav ntawm cov txheej txheem qib, ces lawv tsis muaj kev cuam tshuam loj rau kev ua haujlwm ntawm "kev ua haujlwm". Tab sis muaj kab laum nyob hauv SuperFetch module ua qhov kev pabcuam no tiag tiag tsis qhib. Thiab nyob rau hauv cov ntaub ntawv no, txawm tias nkag mus rau qhov tsim nyog yuav tsum tau nyob rau hauv tib qho kev sau npe tsis pauv qhov xwm txheej rau qhov zoo dua. Feem ntau koj tuaj yeem pom cov lus hais tias muaj qhov txawv txav tsis ua haujlwm (SuperFetch txiav tawm) lossis nkag tsis pom zoo suav daws.
Cov xwm txheej no tshwm sim vim tsis muaj RAM los yog vim muaj kev sib cav ntawm cov "RAM" slats. Hauv qhov no, tsis muaj dab tsi tshuav tab sis mus ua tag qhov kev pabcuam. Yog tias muaj RAM txaus los sim txoj haujlwm ntawm kev pabcuam thiab tshem tawm cov teebmeem nrog nws, ces nws raug nquahu kom ua qhov no. Thiab tom qab qhov kev ua yeeb yam dhau los, koj tuaj yeem tig nws tawm, lossis txuas ntxiv siv nws txuas ntxiv.
SuperFetch ib txwm khiav hauv tom qab. Cov kev pabcuam siv cov txheej txheem tsim cov khoom siv thiab lub cim xeeb. "Superfetch" tsis yog hu kom tshem tawm qhov kev thauj khoom ntawm daim ntawv thov mus rau hauv "RAM", nws lub hom phiaj ncaj qha ua kom cov txheej txheem no nrawm. Thiab txhua txhua lub sijhawm rub tawm, lub kaw lus tseem yuav ua tib yam kev poob qis yog tias daim ntawv thov raug tsim tawm tsis muaj SuperFetch. Qhov no yog vim hais tias cov kev pab cuam thauj khoom ntau heev ntawm cov ntaub ntawv los ntawm lub hard drive mus rau RAM. Thiab yog tias, nrog txhua qhov pib los yog rov pib dua ntawm lub khoos phis tawm, lub hard drive ua haujlwm ntawm ib puas feem pua load rau qee lub sijhawm, ces teeb meem nrog SuperFetch yuav tshwm sim. Cov neeg twvtxiaj nrog plaub gigabytes ntawm lub cim xeeb lossis tsawg dua yuav muaj teebmeem nrog SuperFetch. Lub ntsiab tsis zoo ntawm no yog tias muaj kev ua si siv cov RAM ntau. Hauv qhov no, muaj qhov thov tas mus li thiab pub dawb ntawm lub cim xeeb. Qhov kev ua tiav ntawm kev tswj kom zoo li no tuaj yeem ua rau cov kev pabcuam tas li thauj khoom thiab txo cov ntaub ntawv hauv zos.
Disabling SuperFetch: txhua qhov zoo thiab tsis pom zoo
Coob leej neeg nyob rau niaj hnub no tsis ntseeg qhov kev siv txoj haujlwm no. Nws nquag pom zoo kom tua cov kev pabcuam SuperFetch los txhim kho kev ua haujlwm thiab ua tiav ntawm koj lub khoos phis tawm. Txawm li cas los xij, tsis yog tsuas yog tus neeg siv khoom muaj peev xwm daws tau qhov teeb meem uas tau tshwm sim txog qhov kev qhia tawm ntawm kev siv SuperFetch hauv nws cov xwm txheej.
Kuj tseem muaj kev pom zoo rau txhua tus neeg siv, uas yog raws li hauv qab no:
- qhov me me ntawm RAM tsis tso cai rau siv du ntawm kev pabcuam;
- nws qhov ntim txaus pom zoo kom ua Superfetch.
Yog li, yog tias tus nqi ntawm RAM tsis tshaj 1 GB, thiab lub cim xeeb load tuaj yeem ncav 600 MB, kom tsis txhob hais txog lub cim ntxiv virtual thiab paging ntawv, tom qab ntawd qhov xwm txheej nrog kev txwv RAM ua haujlwm tshwm sim. Tab sis qhov no yog qhov tseeb yog tias lub koos pis tawj yog ntawm lub xyoo qub (readyboost siv). Hauv cov systems niaj hnub, txawm hais tias qhov kev teeb tsa tsawg kawg nkaus siv, snap-hauv kev pib siv ntau ntawm RAM loj, pib ntawm 3 GB. Nyob rau hauv cov ntaub ntawv no, ntawm chav kawm, kev siv ntawm SuperFetch kev pab yog tsis yog. Koj tuaj yeem piv kev ua haujlwm ntawm lub khoos phis tawm ntawm ntau hom: siv SuperFetch thiab thaum nws muab tua. Qee tus neeg siv nco ntsoov tias qhov no lawv tsis pom ntau qhov sib txawv.
Hauv lwm lo lus, kev siv lossis tshem tawm SuperFetch raws li tus tswv tsev yog nyob ntawm qhov sib npaug ntawm qhov muaj peev xwm thiab qhov kev cia siab nyob ntawm lub khoos phis tawm RAM. Yog lawm, thaum siv cov kev ua si niaj hnub ntawm kev kho vajtse qub, teeb meem nrog kev ua haujlwm ntawm lub operating system yog kev tsis tuaj yeem dhau. Txawm li cas los xij, nyob rau lwm qhov, thaum lub RAM daws nrog lub luag haujlwm tsis muaj teeb meem, tsuas yog tsis tas yuav tsum nce qhov ceev ntawm lub koos pij tawj los ntawm kev xiam oob qhab cov txheej txheem.
