Vanogadzira Canonical vakaburitswa kuburikidza neLinux kernel yekuvandudza tsamba yekutumira, seti yezvimedu zve kuitwa kwe kunatsa kuyeuka ndangariro, iyo inovavarira ku zvakanyanya kudzora nguva yekurara yehurongwa.
Kugadziridza inowanikwa kubudikidza nekushingairira kukumbira kuburitswa kwendangariro zvimiro vana vasina ruzivo rwakasiyana uye vanokwanisa kudzoreredzwa mushure mekudzoka kubva kuhope modhi (semuenzaniso, nzvimbo dzisingazivikanwe ndangariro uye akawanda memory peji kacheji).
Nezve zvigamba
Pfungwa huru ndeyekuti mushure mekubvisa zvisina basa data, ndangariro yemufananidzo saizi inoderedzwa kuponesar usati warara mode uye nekudaro nguva shoma inodiwa kunyora nekuverenga kubva pane inononoka svikiro.
Default, kana uchichengeta memory dump yemhando yekurara, iyo kernel inochengetedza ndangariro zviri sei neese macache, asi pane mukana wakajairika wekuburitsa Izvo zvisina kufanira zvivakwa zvinoteedzera zvisina kukwana zviwanikwa mamiriro mune yekutanga nhanho yekuchinjira kune yekurara modhi.
Ichi chimiro inogona kumisikidzwa uchishandisa paramende "/ sys / simba / image_size" uye inotungamira kudzikisira kunoonekwa munguva yekuenda kunorara maitiro.
Canonical inoratidza kuwedzera mamwe maviri ma parameter, iyo inobvumidza kuburitswa kweasina kufanira zvivakwa pamberi kuitira kuti iko chaiko shanduko yekurara nzira yapedzwa nekukurumidza sezvinobvira uye kudzoka kubva kuhope maitiro kwakatora ingangoita yakaenzana nguva senge apo panoshandiswa paramende.
Miedzo uye mhedzisiro
Kuedzwa pane system ine 8 GB ye RAM uye iyo 8 GB chinjana chikamu paunenge uchishandisa 85% yekurangarira yakaratidza mune default masetingi (image_size = default) kuderera kwenguva kuenda kunorara mode kubva pa51.56 kuenda ku4.19 masekondi apo iyo yekuwandisa ndangariro yekuchenesa maitiro yakatanga masekondi makumi matanhatu usati wachinjira kunzira yekurara.
Nekuda kwekudzikiswa kwehukuru hweiyo yakachengetedzwa memory memory, iyo nguva yekudzosa yakaderera kubva pa26.34 kusvika pamasekonzi mashanu.
Heano wekutanga kuedza kupa chinongedzo icho chinobvumidza mushandisi nzvimbo mabasa kukonzeresa mukana mukana ndangariro kudzokorodza usati wavhiringidza system.
Kurangarira ndangariro pamberi (semuenzaniso, kana iyo system isingashandi) inobvumira
deredza saizi yemufananidzo wehibernation uye nekukurumidza kumhanyisa iyo hibernation uye kutangazve nguva.
Kana yakajairika yekuchenesa modhi yekuwedzera ndangariro (mufananidzo_size = 0) yakagoneswa pane system, iyo nguva yekuenda kunorara modhi yakaderera kubva pa73.22 kusvika 5.36 masekondi uye nguva yekudzoka kubva kurara maitiro haina kuchinja (yakaderera nechikamu chidiki chechipiri, kubva pa5.32 kusvika 5.26 masekondi).
Iyo yakajairika kesi yekushandisa yeichi chiitiko ndeyekutendera yakakwira-kukoshesa gore zviitiko kuti zviwane zvakaderera-zvakakosha zviitiko (semuenzaniso, nzvimbo dzenzvimbo [1]) nekuzvidzikisira.
Opportunistic memory reclamation inoshanda zvakanyanya mukukurumidza hibernating zviitiko izvo zvinopa huwandu hwakawanda hwendangariro uye hunogara kazhinji husina basa nguva zhinji, uchishandisa chete mashoma mashandiro seti.
Shandisa
Iyo nzira yakatsanangurwa inogona kukumbirwa mumamiriro ezvinhu panofanirwa kuenda nekukurumidza kunorara modhi uye zvinokwanisika kufungidzira kudiwa kweshanduko yakadaro pamberi.
Semuenzaniso, mumasisitimu egore, akadzika-epamberi mamiriro enzvimbo (nongedzo nharaunda muAmazon EC2) anogona zvine simba kupinda muhusiku uye kusunungura ndangariro dzakagamuchirwa sekushandiswa kwezvishandiso zvekutanga zvinokura.
Kana mutoro wacho waderedzwa muzvirongwa zvekutanga, nharaunda dzakakoshesa pekutanga dzinodzoka kubva munzira yekurara. Mune aya mamiriro, kuchengetedza yakakwana mhando yebasa, zvakakosha kudzikisira nguva yekupinda uye kubuda nzira yekurara.
Chikamu chekudzivirira chekuchenesa chinogona kutanga kana imwe nhanho yemutoro mukuru yasvika, iyo inotangira nhanho inotungamira mukutonhora kwenzvimbo dzakaderera zvakanyanya.
