D\u00e9veloppeurs d'Arch Linux sur le site de l'entreprise. D\u00e9sormais, les utilisateurs peuvent ajouter un nombre illimit\u00e9 de morceaux \u00e0 leur biblioth\u00e8que.<\/a><\/noindex>, qui ont modifi\u00e9 le sch\u00e9ma d'emballage des paquets en changeant d'algorithme. L'algorithme xz (.pkg.tar.xz) \u00e9tait auparavant utilis\u00e9. D\u00e9sormais, zstd (.pkg.tar.zst) est utilis\u00e9. Cela a permis d'augmenter la vitesse de d\u00e9compression de 1300 % pour un l\u00e9ger augment de la taille des paquets eux-m\u00eames (environ 0,8 %). Cela va acc\u00e9l\u00e9rer le processus d'installation et de mise \u00e0 jour des paquets dans le syst\u00e8me.<\/p>\n

\"Arch<\/p>\n

Actuellement, il est question de la conversion de 545 paquets vers zstd. Les autres recevront progressivement le nouvel algorithme de compression au fur et \u00e0 mesure des mises \u00e0 jour. Il est important de noter que les paquets au format .pkg.tar.zst sont automatiquement pris en charge avec les mises \u00e0 jour de pacman (5.2) et libarchive (3.3.3-1). Si certains utilisateurs n'ont pas encore mis \u00e0 jour libarchive, la nouvelle version est disponible dans un d\u00e9p\u00f4t distinct.<\/p>\n

L'algorithme zstd (zstandard) a \u00e9t\u00e9 d\u00e9velopp\u00e9 en 2015 et pr\u00e9sent\u00e9 pour la premi\u00e8re fois l'ann\u00e9e suivante. Il permet une compression sans perte et est ax\u00e9 sur une vitesse de compression et de d\u00e9compression plus \u00e9lev\u00e9e que d'habitude. Le ratio de compression doit \u00eatre comparable ou sup\u00e9rieur aux solutions existantes. Comme l'indique la version zstd 0.6, celle-ci, avec le niveau de compression maximal, a obtenu des r\u00e9sultats similaires \u00e0 ceux de boz, yxz, tornado. En revanche, elle a surpass\u00e9 lza, brotli et bzip2.<\/p>\n
