Entwickler von Arch Linux berichteten<\/a><\/noindex>, dass das Verpackungsschema der Pakete ge\u00e4ndert wurde. Fr\u00fchere verwendete den Algorithmus xz (.pkg.tar.xz). Jetzt wird zstd (.pkg.tar.zst) verwendet. Dies erm\u00f6glicht eine Steigerung der Entpackgeschwindigkeit um 1300 %, bei einem nur geringf\u00fcgigen Anstieg der Paketgr\u00f6\u00dfe (ungef\u00e4hr 0,8 %). Dies wird den Installations- und Aktualisierungsprozess der Pakete im System beschleunigen.<\/p>\n

\"Arch<\/p>\n

Derzeit wird \u00fcber die \u00dcbersetzung von zstd in 545 Pakete gesprochen. Die anderen werden allm\u00e4hlich den neuen Komprimierungsalgorithmus mit den kommenden Updates erhalten. Dabei ist wichtig zu beachten, dass Pakete im .pkg.tar.zst Format automatisch unterst\u00fctzt werden, sofern Updates f\u00fcr pacman (5.2) und libarchive (3.3.3-1) vorhanden sind. Falls jedoch einer der Benutzer libarchive noch nicht aktualisiert hat, ist die neue Version in einem separaten Repository verf\u00fcgbar.<\/p>\n

Der Algorithmus zstd (zstandard) wurde 2015 entwickelt und ein Jahr sp\u00e4ter erstmals vorgestellt. Er erm\u00f6glicht verlustfreie Komprimierung und zielt auf h\u00f6here Komprimierungs- und Dekomprimierungsgeschwindigkeiten ab als \u00fcblich. Dabei sollte der Kompressionsfaktor vergleichbar oder besser sein als bei bestehenden L\u00f6sungen. Es wurde festgestellt, dass die Version zstd 0.6 bei maximaler Komprimierung ein \u00e4hnliches Ergebnis wie boz, yxz und tornado lieferte und dabei lza, brotli und bzip2 \u00fcbertraf.<\/p>\n
