Abathuthukisi be-Canonical bakhishiwe ngokusebenzisa uhlu lwamakheli wokuthuthukiswa kwe-Linux kernel, iqoqo lezimagqabhagqabha ze ukuqaliswa kwe- ukuhlanza inkumbulo okungosomathuba, okuhlose uku ukunciphisa kakhulu isikhathi sokulala yohlelo.
Ukusebenziseka kutholakala ngokucela ngamandla ukukhululwa kwezakhiwo zememori izingane ezingenalo ulwazi oluyingqayizivele nolungabuyiselwa ngamandla ngemuva kokubuya kwimodi yokulala (ngokwesibonelo, izindawo zememori ezingaziwa kanye nezinqolobane zekhasi lememori eziningi)
Mayelana nezimagqabhagqabha
Umqondo oyinhloko ukuthi ngemuva kokususa idatha engadingekile, usayizi wesithombe sememori wehlisiwe ukusindisar ngaphambi kokulala imodi futhi ngenxa yalokho isikhathi esincane siyadingeka ukubhala nokufunda kumphakathi ohamba kancane.
Okuzenzakalelayo, lapho ugcina indawo yokulahla inkumbulo ngemodi yokulala, i-kernel igcina inkumbulo kunjani ngawo wonke ama-cache, kodwa kunethuba elijwayelekile lokukhululwa Izakhiwo ezingadingeki ezilingisa izimo zensiza ezinganele esigabeni sokuqala sokushintshela kwimodi yokulala.
Lesi sici ingenziwa isebenze kusetshenziswa ipharamitha "/ sys / power / image_size" futhi kuholela ekwehliseni okubonakalayo esikhathini sokuya kumodi yokulala.
ICanonical isikisela ukungeza eminye imingcele emibili, okuzovumela ukukhishwa kwezakhiwo ezingadingeki kusengaphambili ukuze ushintsho lwangempela kwimodi yokulala luqedwe ngokushesha okukhulu futhi ukubuya kwimodi yokulala kuthathe isikhathi esilinganayo nesikhathi lapho kusetshenziswa ipharamitha.
Ukuhlolwa nemiphumela
Ukuhlolwa kusistimu ene-8 GB ye-RAM kanye nokwahlukanisa okungu-8 GB ngenkathi usebenzisa inkumbulo engama-85% kuboniswe kuzilungiselelo ezizenzakalelayo (image_size = default) ukwehla kwesikhathi ukuya kwimodi yokulala kusuka ku-51.56 kuya ku-4.19 imizuzwana lapho inqubo yokuhlanza inkumbulo eyeqile iqalile imizuzwana engama-60 ngaphambi kokushintshela kumodi yokulala.
Ngenxa yokwehla kobukhulu besithombe sememori esilondoloziwe, isikhathi sokutakula sehle sisuka kumasekhondi angama-26.34 kuye kwayi-5.
Nanku umzamo wokuqala wokunikeza isikhombimsebenzisi esivumela imisebenzi yesikhala somsebenzisi ukuthi ibangele ukuvuselelwa kwememori engamathuba ngaphambi kokufihla uhlelo.
Ukukhumbula inkumbulo kusengaphambili (isb., Lapho uhlelo lungangenzi lutho) kuvumela
nciphisa usayizi wesithombe se-hibernation futhi usheshise kakhulu ubusika futhi uqhubeke nesikhathi.
Lapho imodi ejwayelekile yokuhlanza ngememori eyeqile (image_size = 0) inikwe amandla ohlelweni, isikhathi sokuya kwimodi yokulala yehle isuka kumasekhondi angu-73.22 yaya ku-5.36 nesikhathi sokubuya kwimodi yokulala asishintshanga (sehle ngocezu lwesekhondi kuphela, kusuka kumasekhondi angu-5.32 kuye kwayisi-5.26).
Isimo esivamile sokusetshenziswa kwalesi sici ukuvumela izimo zefu ezisezingeni eliphakeme ukudlula izimo ezibaluleke kakhulu (ngokwesibonelo, izindawo ezibonwayo [1]) ngokuzichitha.
Ukuvuselelwa kwememori okunenzuzo kusebenza kahle ezimeni zokufihla ngokushesha ezinikezela ngenqwaba yememori futhi zihlala zingenzi lutho isikhathi esiningi, kusetshenziswa isethi yokusebenza okuncane kuphela.
Sebenzisa
Indlela ehlongozwayo ingacelwa ezimeni lapho kudingeka khona ukuya ngokushesha kumodi yokulala futhi kungenzeka ukuthi ulindele isidingo soshintsho olunjalo kusengaphambili.
Isibonelo, ezinhlelweni zamafu, izindawo ezibonakalayo ezisezingeni eliphansi (izindawo zamaphoyinti e-Amazon EC2) zingangena ngamandla ebusika futhi zikhulule imemori ehlala abantu njengoba ukusetshenziswa kwezinsizakusebenza kukhula.
Lapho umthwalo usunciphile kuzilungiselelo eziyinhloko, izindawo ezisezingeni eliphansi zibuya kumodi yokulala. Kulezi zimo, ukugcina insizakalo eyanele, kubalulekile ukunciphisa isikhathi sokungena nokuphuma kumodi yokulala.
Isigaba sokuhlanza esivimbelayo singaqalwa lapho kufinyelelwa ezingeni elithile lomthwalo omkhulu, olandulela izinga eliholela ekubandeni kwezindawo ezisezingeni eliphansi.
