Arch Linux has switched to using the zstd algorithm for package compression.

Posted on

Arch Linux developers announced the transition of the package packaging scheme from the xz algorithm (.pkg.tar.xz) to zstd (.pkg.tar.zst). The repackaging of the packages into the zstd format resulted in a total package size increase of 0.8%, but improved unpacking speed by 1300%. As a result, the switch to zstd will lead to a significant increase in package installation speed. Currently, the repository uses the algorithm […]
