Ontwikkelaars van Arch Linux hebben aangegeven<\/a><\/noindex>, dat ze de verpakkingsschema's van pakketten hebben gewijzigd van het algoritme. Voorheen werd het xz-algoritme (.pkg.tar.xz) gebruikt. Nu wordt zstd (.pkg.tar.zst) ingezet. Dit heeft geleid tot een 1300% snellere uitpak-snelheid met een geringe toename van de grootte van de pakketten (ongeveer 0,8%). Dit zal het installatie- en updateproces van pakketten in het systeem versnellen.<\/p>\n

\"Arch<\/p>\n

Momenteel wordt er gesproken over de vertaling van 545 pakketten naar zstd. De andere zullen geleidelijk de nieuwe compressie-algoritme ontvangen naarmate updates worden uitgebracht. Het is belangrijk op te merken dat pakketten in .pkg.tar.zst-indeling automatisch worden ondersteund bij beschikbare updates van pacman (5.2) en libarchive (3.3.3-1). Als een van de gebruikers libarchive nog niet heeft bijgewerkt, is de nieuwe versie beschikbaar in een aparte repository.<\/p>\n

Het zstd (zstandard) algoritme werd in 2015 ontwikkeld en voor het eerst gepresenteerd een jaar later. Het biedt verliesloze compressie en is gericht op een hogere compressie- en decompressiesnelheid dan gebruikelijk. De compressieverhouding moet vergelijkbaar zijn met of beter zijn dan bestaande oplossingen. Zoals opgemerkt, vertoonde versie zstd 0.6 bij maximale compressiegraad vergelijkbare resultaten als boz, yxz en tornado. Tegelijkertijd overtrof het lza, brotli en bzip2.<\/p>\n
