 ### Differences to xz
 
 -   `pixz` automatically indexes tarballs during compression
+-   `pixz` supports parallel decompression, which `xz` does not
 -   `pixz` defaults to using all available CPU cores, while `xz` defaults to using only one core
 -   `pixz` provides `-i` and `-o` command line options to specify input and output file
 -   `pixz` does not support the command line option `-z` or `--compress`
