Ezinsukwini ezimbalwa ezedlule kwenziwa okuthunyelwe esithangamini se-Ubuntu, okuyinto yenaAbathuthukisi be-Canonical baqaphele ukuthi imvelo yedeskithophu "Igobolondo le-Gnome" ku-Ubuntu inguqulo 19.04, okususelwa kuGnome 3.32, ibihamba kancane ngokuphawulekayo kunezinye izindawo zedeskithophu.
Ekuqaleni bekucatshangwa ukuthi isizathu ukusetshenziswa kweJavaScript, kepha kwavela ukuthi iJavaScript yayingamaphesenti ayishumi kuphela ekhodi ekuhlanganisweni kweGnome Shell kanye nomphathi wewindi leMutter nokuthi empeleni lokhu kwakungeyona imbangela yokuhamba kancane okubonakalayo.
Ukucabanga okulandelayo ukuthi isoftware yayilayisha ngokweqile i-CPU noma ikhadi lehluzo. Kepha izilinganiso zikhombisile ukuthi lokhu bekungenjalo. Okuvele esikhundleni salokho ukuthi abaprosesa baphoqeleka ukuba bahlale bengenzi lutho isikhathi eside.
Into ebalulekile okufanele uyiqaphele lapha ukuthi iningi lekhodi yomthombo iphrojekthi ye-Mutter, hhayi iGnome Shell. Ngakho-ke, cishe kuphela i-10% yeGnome Shell ebhalwe kwiJavaScript lapho ubheka iMutter, futhi cishe i-90% ibhalwe ku-C.
Ngakho-ke, Onjiniyela bakwazi ukugxila ocwaningweni lwabo ngesikhathi, okukhulunywa ngakho esihlokweni ngokuthi "isikhathi sangempela." Ngoba iGnome neMutter bacubungula i-loop yomcimbi I-Glib ngayinye ngentambo eyodwa, bathambekele ekubambezelekeni.
Noma ikuphi ukubambezeleka okude kungadala ukuthi eyodwa yozimele yeqwe ezakha isithombe kuqapha. Lokhu kubonakala ngokulahla okuphawuleka komsebenzisi okuqapha.
Ngokulinganisa ama-lags ahlukahlukene, abathuthukisi bathole izimbungulu ze-Gnome ezingekho ngaphansi kwesigamu ezilungiswe eGnome 3.34.
Iphutha lokuqala liholele ekweqekeni kozimele ngoba ngemuva kokubambezeleka kohlelo lohlaka ngama-millisecond ambalwa, isikhathi lapho uzimele obekumele lwakhiwe kabusha sabalwa ngokungafanele.
Kepha ukulungisa leli phutha, ebelingaveli njalo, lenze isethulo sibe bushelelezi kakhulu.
Okwesibili, lAbathuthukisi bathole ukuthi cishe wonke amafreyimu abambezelekile ku-X.org ngoba ukubalwa kwetafula kusethwe kusenesikhathi. Ngezinga lohlaka lwama-60 Hz, isikrini sibambezeleke ngama-16 ms.
Kulokhu iWayland ayithinteki. Elinye iphutha liphathelene neWayland kuphela. Inkinga bekuwukuthi kwaMutter, isivinini sokubonisa isikhombisi segundane sasethwe saya ku-60Hz. Lokhu kungadala izinkinga ezifika ku-100% ukusetshenziswa kwe-CPU uma isilinganiso sokuvuselela sihlukile.
Futhi UMutter ubenenye inkinga ebisencazululwe kancane kuze kube manje. Njengomphumela, yonke imicimbi yokufaka ibambezelekile kufreyimu elandelayo, okusho ukuthi, kuze kufike ku-16 ms kuma-60 Hz.
Okunye ukubambezeleka kudalwe ukulungiswa kwabashayeli beNvidia abaphethe i-X.org, okungasadingeki manje.
Futhi enye inkinga yagqanyiswa, inquma ukuthi yini ethinta isikhombisi segundane, lapho kwenziwa khona izingcingo ze-OpenGL, lokhu kuthinta ngokweqile futhi kubangele izikhathi ezingeziwe zokulinda ngenxa yokuvumelanisa okudingekayo phakathi kwe-CPU ne-GPU.
Ngenxa yalokho, IGnome 3.34 ishesha kakhulu. Ya okungenani ezinye izindaba ezimbili ziyaziwa ezingakaxazululwa.
- Lapho usebenzisa ama-monitors amaningi, ukushayeka emuva kwe-Wayland kubangela ukubambezeleka okukhulu. Lokhu kufanele kulungiswe ngokusho konjiniyela ku-Gnome 3.36 futhi kanjalo naku-Ubuntu 20.04.
- Inkinga yesibili ukuthi akukhona konke ukubambezeleka eMutter okuxazululiwe okwamanje. I-athikili iphetha ngamathiphu wokuthi yimaphi amaphutha okufanele uwagweme lapho uxazulula inkinga nombono wokuthi yini okufanele uyenze ngokulandelayo.
Ukuthuthukisa IGnome kufanele ibe ye-Ubuntu 20. 04 kuningi lokuthuthuka Yini okufanele bagxile kuyo? kwi-hardware yesimanje futhi esheshayo. Izingqinamba ezisele ezithinta amakhompyutha amadala futhi ahamba kancane kudingeka zilungiswe futhi zixazululwe ku-Ubuntu 20.10.
Uma ufuna ukwazi kabanzi ngokushicilelwa, ungabheka isixhumanisi esilandelayo.
