Arch Linuxi arendajad teatasid<\/a><\/noindex>, et muudeti pakettide pakkimise skeemi algoritmi. Varem kasutati algoritmi xz (.pkg.tar.xz). N\u00fc\u00fcd on kehtestatud zstd (.pkg.tar.zst). See on v\u00f5imaldanud suurendada paketide lahtipakkimise kiirus 1300% v\u00f5rra, mis toob kaasa ebaolulise pakettide suuruse suurenemise (umbes 0,8%). See kiirendab pakettide installimise ja uuendamise protsessi s\u00fcsteemis.<\/p>\n

\"Arch<\/p>\n

Praegu on k\u00f5neldud 545 paketi \u00fcleviimisest zstd formaati. \u00dclej\u00e4\u00e4nud hakkavad j\u00e4rk-j\u00e4rgult saama uut tihendamist, kui v\u00e4rskendused v\u00e4lja tulevad. Oluline on m\u00e4rkida, et .pkg.tar.zst formaadis paketid toetavad automaatselt v\u00e4rskendusi, kui on olemas pacman (5.2) ja libarchive (3.3.3-1). Kui aga m\u00f5ni kasutaja ei ole veel libarchive'i uuendanud, siis uus versioon on saadaval eraldi hoidlas.<\/p>\n

Zstd (zstandard) algoritm loodi 2015. aastal ja esmakordselt esitati see j\u00e4rgmisel aastal. See lubab kadudeta tihendamist ning on suunatud k\u00f5rgemale tihendamise ja dekompressimise kiirus\u0435, kui tavaliselt. Tihenduskoefitsient peaks olema v\u00f5rreldav v\u00f5i \u00fcletama olemasolevaid lahendusi. Nagu m\u00e4rgitud, n\u00e4itas zstd 0.6 maksimaalse tihendamise astmega sarnaseid tulemusi nagu boz, yxz, tornado. Samuti \u00fcletas see lza, brotli ja bzip2.<\/p>\n
