Abaphuhlisi beCanonical bakhululwa Ngoluhlu lokuposa lwe-Linux kernel, iseti yeepatches ze ukumiliselwa kwe ukucoca inkumbulo, ejolise ku ukunciphisa kakhulu ixesha lokulala yenkqubo.
Ukulungiswa kufezekiswa ngokubhengeza ngamandla ukukhutshwa kwezakhiwo zememori abantwana abangenalo ulwazi olwahlukileyo nolunokubuyiselwa ngamandla emva kokubuya kwimowudi yokulala (umzekelo, iindawo zememori ezingaziwayo kunye neenqolobane zamaphepha ememori).
Malunga neepatches
Owona mbono uphambili kukuba emva kokucima idatha engeyomfuneko, ubungakanani bomfanekiso wememori buncitshisiwe ukugcunar ngaphambi kokuba ulale imowudi kwaye ngenxa yoko lixa elincinci elifunekayo ukubhala kunye nokufunda kulwimi olucothayo.
Ukungagqibeki, xa ugcina indawo yokulahla inkumbulo kwimowudi yokulala, i-kernel igcina inkumbulo kunjani kuzo zonke iicachekodwa kukho imeko esemgangathweni yokukhutshwa Ulwakhiwo olungeyomfuneko olulinganisa iimeko zoncedo ezingonelanga kwinqanaba lokuqala lenguqu kwimowudi yokulala
Eli nqaku ingenziwa isebenze iparameter "/ sys / power / image_size" kwaye ikhokelela kunciphiso olubonakalayo kwixesha lokuya kwimodi yokulala.
I-Canonical icebisa ukongeza ezinye iiparameter, eya kuthi ivumele ukukhutshwa kwezakhiwo ezingeyomfuneko kwangaphambili ukuze olona tshintsho lwendlela yokulala lugqitywe ngokukhawuleza kwaye ukubuya kwimowudi yokulala kuthathe malunga nexesha elifanayo njengoko kusetyenziswa ipharamitha.
Uvavanyo kunye neziphumo
Ukuvavanywa kwenkqubo ene-8 GB ye-RAM kunye ne-8 GB yokutshintsha ukwahlula ngelixa usebenzisa i-85% yememori iboniswe kuseto olungagqibekanga (image_size = emiselweyo) ukuncipha kwexesha ukuya kwimowudi yokulala isuka kwi-51.56 ukuya kwi-4.19 imizuzwana xa inkqubo yokugcina imemori yokucoca iqale imizuzwana engama-60 ngaphambi kokutshintshela kwimowudi yokulala.
Ngenxa yokuncitshiswa kobungakanani bemifanekiso egciniweyo yememori, ixesha lokubuyisela linciphile ukusuka kwi-26.34 ukuya kwimizuzwana emi-5.
Nalu umzamo wokuqala wokubonelela ujongano oluvumela imisebenzi yendawo yomsebenzisi ukuba ibangele ukuphindaphinda kwimemori ngaphambi kokufihla inkqubo.
Ukukhumbula inkumbulo kwangaphambili (umzekelo, xa inkqubo ingasebenzi) ivumela
ukunciphisa ubungakanani bomfanekiso we-hibernation kunye nokukhawulezisa kakhulu ubusika kunye nokuqhubeka kwexesha.
Xa indlela yokucoca eqhelekileyo kwimemori engaphezulu (umfanekiso_size = 0) yenziwe kwinkqubo, ixesha lokuya kwimodi yokulala yehlile ukusuka kwi-73.22 ukuya kwi-5.36 imizuzwana kwaye ixesha lokubuya kwimowudi yokulala alitshintshanga (lehle ngamaqhezu omzuzwana, ukusuka kwimizuzwana emi-5.32 ukuya 5.26).
Ityala eliqhelekileyo lokusetyenziswa kweli nqaku kukuvumela iimeko zelifu eziphambili kakhulu ukuba zigqithise iimeko ezisezantsi (umzekelo, iimeko zeendawo [1]) ngokuzifihla.
Ukuphindaphinda inkumbulo esebenzayo kuyasebenza kakhulu kwimeko yokufihla ngokukhawuleza eyabela isixa esikhulu sememori kwaye ihlala ingasebenzi ixesha elininzi, isebenzisa kuphela iseti yokusebenza encinci.
Sebenzisa
Indlela ecetywayo inokucelwa kwiimeko apho kuye kufuneke ukuba kukhawuleziswe ukuya kwimo yokulala kwaye kunokwenzeka ukuba ulindele kwangaphambili isidingo sotshintsho kwangaphambili.
Umzekelo, kwiinkqubo zamafu, imeko-bume ephantsi ekubekwa phambili kuyo (indawo yeAmazon EC2) zinokungena ngamandla kwi-hibernation kwaye zikhulule imemori ekuhlalwa kuyo njengoko ukusetyenziswa kwezixhobo eziphambili kusanda.
Xa umthwalo uncitshisiwe kuseto oluphambili, iimeko eziphambili ngokubaluleka zibuya kwindlela yokulala. Kule meko, ukugcina umgangatho wenkonzo owaneleyo, kubalulekile ukunciphisa ixesha lokungena kunye nokuphuma kwimodi yokulala.
Inqanaba lokucoca linokuqaliswa xa kufikwa kwinqanaba elithile lomthwalo ophambili, ophambi kwenqanaba elikhokelela ekubandeni kwemimandla ephantsi.
