Firma Canonical rozpocz\u0119\u0142a prac\u0119 nad rozwi\u0105zaniem problem\u00f3w z wydajno\u015bci\u0105 pakietu snap z Firefoxem, kt\u00f3ry zosta\u0142 domy\u015blnie zaproponowany w Ubuntu 22.04 zamiast tradycyjnego pakietu deb. G\u0142\u00f3wne niezadowolenie u\u017cytkownik\u00f3w dotyczy bardzo d\u0142ugiego czasu startu Firefoxa. Na przyk\u0142ad na laptopie Dell XPS 13 pierwsze uruchomienie Firefoxa po instalacji zajmuje 7,6 sekundy, na laptopie Thinkpad X240 \u2014 15 sekund, a na p\u0142ycie Raspberry Pi 400 \u2014 38 sekund. Kolejne uruchomienia odbywaj\u0105 si\u0119 ju\u017c w czasie 0,86, 1,39 i 8,11 sekundy odpowiednio. <\/p>\n
Podczas analizy problemu zidentyfikowano 4 g\u0142\u00f3wne przyczyny wolnego uruchamiania, kt\u00f3rym zostanie po\u015bwi\u0119cona szczeg\u00f3lna uwaga: <\/p>\n
Podczas uruchamiania Firefox z pakietu snap zaobserwowano r\u00f3wnie\u017c pewne problemy z wydajno\u015bci\u0105 podczas pracy, ale programi\u015bci Ubuntu ju\u017c przygotowali poprawki, kt\u00f3re poprawiaj\u0105 wydajno\u015b\u0107. Na przyk\u0142ad od wersji Firefox 100.0 w konstrukcji w\u0142\u0105czono optymalizacje na etapie linkowania (LTO) oraz na podstawie wynik\u00f3w profilowania kodu (PGO). Aby rozwi\u0105za\u0107 problemy z komunikacj\u0105 mi\u0119dzy Firefox a zewn\u0119trznymi podsystemami, przygotowano nowy portal XDG Desktop, kt\u00f3rego wsparcie jest obecnie w fazie przegl\u0105du przed w\u0142\u0105czeniem do Firefox. <\/p>\n
Przyczynami promowania formatu snap dla przegl\u0105darek jest ch\u0119\u0107 uproszczenia konserwacji i ujednolicenia rozwoju dla r\u00f3\u017cnych wersji Ubuntu \u2014 pakiet deb wymaga osobnej konserwacji dla wszystkich wspieranych ga\u0142\u0119zi Ubuntu, co wi\u0105\u017ce si\u0119 ze sk\u0142adaniem i testowaniem z uwzgl\u0119dnieniem r\u00f3\u017cnych wersji komponent\u00f3w systemowych, natomiast pakiet snap mo\u017ce by\u0107 tworzony jednocze\u015bnie dla wszystkich ga\u0142\u0119zi Ubuntu. Co wi\u0119cej, oferowany w Ubuntu pakiet snap z Firefoxem jest wspierany przez pracownik\u00f3w Mozilli, co oznacza, \u017ce jest tworzony z pierwszej r\u0119ki bez po\u015brednik\u00f3w. Dostarczenie w formacie snap umo\u017cliwi\u0142o r\u00f3wnie\u017c szybsze wprowadzenie nowych wersji przegl\u0105darki do u\u017cytkownik\u00f3w Ubuntu oraz pozwoli\u0142o uruchamia\u0107 Firefoxa w izolowanym \u015brodowisku, stworzonym za pomoc\u0105 mechanizmu AppArmor, zapewniaj\u0105c dodatkow\u0105 ochron\u0119 reszty systemu przed wykorzystaniem luk w przegl\u0105darce.
