Az Arch Linux fejleszt\u0151i bejelentett\u00e9k<\/a><\/noindex>, ami megv\u00e1ltoztatta a csomagok t\u00f6m\u00f6r\u00edt\u00e9si s\u00e9m\u00e1j\u00e1t. Kor\u00e1bban az xz algoritmus volt haszn\u00e1latban (.pkg.tar.xz). Mostant\u00f3l a zstd algoritmus van \u00e9rv\u00e9nyben (.pkg.tar.zst). Ez 1300%-kal megn\u00f6velte a kibont\u00e1si sebess\u00e9get, cser\u00e9be a csomagok m\u00e9ret\u00e9nek enyhe n\u00f6veked\u00e9se (kb. 0,8%) mellett.

Jelenleg a zstd-re m\u00e1r 545 csomag ford\u00edt\u00e1s\u00e1r\u00f3l van sz\u00f3. A t\u00f6bbi fokozatosan megkapja az \u00faj t\u00f6m\u00f6r\u00edt\u00e9si algoritmust a friss\u00edt\u00e9sek megjelen\u00e9s\u00e9vel. Fontos megjegyezni, hogy a .pkg.tar.zst form\u00e1tum\u00fa csomagok automatikusan t\u00e1mogatottak a pacman (5.2) \u00e9s libarchive (3.3.3-1) friss\u00edt\u00e9seivel. Ha valaki m\u00e9g nem friss\u00edtette a libarchive-t, az \u00faj verzi\u00f3 k\u00fcl\u00f6n rep\u00f3ban el\u00e9rhet\u0151.<\/p>\n

A zstd (zstandard) algoritmust 2015-ben fejlesztett\u00e9k ki, \u00e9s egy \u00e9vvel k\u00e9s\u0151bb mutatt\u00e1k be.

Ahogy megjegyzik, a zstd 0.6 maxim\u00e1lis t\u00f6m\u00f6r\u00edt\u00e9si fokozat mellett hasonl\u00f3 eredm\u00e9nyeket mutatott a boz, yxz \u00e9s tornado algoritmusokkal, mik\u00f6zben fel\u00fclm\u00falta az lza, brotli \u00e9s bzip2 teljes\u00edtm\u00e9ny\u00e9t.<\/p>\n
