Desarrolladores de Arch Linux informaron<\/a><\/noindex>, que se cambi\u00f3 el esquema de empaquetado de paquetes del algoritmo. Anteriormente se utilizaba el algoritmo xz (.pkg.tar.xz). Ahora se utiliza zstd (.pkg.tar.zst). Esto ha permitido aumentar la velocidad de descompresi\u00f3n en un 1300 % con un incremento insignificante en el tama\u00f1o de los paquetes (aproximadamente un 0,8 %). Esto permitir\u00e1 acelerar el proceso de instalaci\u00f3n y actualizaci\u00f3n de paquetes en el sistema.<\/p>\n

\"Arch<\/p>\n

En este momento se habla de la traducci\u00f3n de 545 paquetes al zstd. Los dem\u00e1s recibir\u00e1n gradualmente el nuevo algoritmo de compresi\u00f3n a medida que se lancen actualizaciones. Es importante destacar que los paquetes en formato .pkg.tar.zst son compatibles autom\u00e1ticamente cuando hay actualizaciones de pacman (5.2) y libarchive (3.3.3-1). Si alguno de los usuarios a\u00fan no ha actualizado libarchive, la nueva versi\u00f3n est\u00e1 disponible en un repositorio separado.<\/p>\n

El algoritmo zstd (zstandard) fue desarrollado en 2015 y se present\u00f3 por primera vez un a\u00f1o despu\u00e9s. Prev\u00ea la compresi\u00f3n sin p\u00e9rdidas y est\u00e1 orientado a ofrecer una velocidad de compresi\u00f3n y descompresi\u00f3n m\u00e1s alta que lo habitual. Adem\u00e1s, se espera que el ratio de compresi\u00f3n sea comparable o superior a las soluciones existentes. Como se se\u00f1ala, la versi\u00f3n zstd 0.6 al m\u00e1ximo nivel de compresi\u00f3n mostraba resultados similares a boz, yxz, tornado. Mientras tanto, superaba a lza, brotli y bzip2.<\/p>\n
