 Arch Linux added support for zstd as a package compression method in October 2019 with the release of the pacman 5.2 package manager, and in January 2020 switched from xz to zstd for the packages in the official repository.Arch uses codice_1, the size of all compressed packages combined increased by 0.8% (compared to xz), the decompression speed is 1300% faster, decompression memory increased by 50 MiB when using multiple threads, compression memory increases but scales with the number of threads used.Full implementation of the algorithm with an option to choose the compression level is used in the .NSZ / .XCZ file formats, developed by the homebrew community for the Nintendo Switch hybrid game console.
