Its ability to compress depends on the compression program you use. Using the 'z' flag specifies that it use gzip, which only uses one core. Use a different compression program. I use lbzip2, there are other options: https://www.linuxlinks.com/best-linux-multi-core-compression-tools/ Once installed, I create an alias like so: alias pzstar='/usr/bin/star compress-program=lbzip2 -sparse' Notice I am using 'star' rather than 'tar' but they are similar. The option for specifying the compress program in tar is so: -I, --use-compress-program=COMMAND Filter data through COMMAND. It must accept the -d option, for decompression. The argument can contain command line options. _______________________________________________ users mailing list -- users@xxxxxxxxxxxxxxxxxxxxxxx To unsubscribe send an email to users-leave@xxxxxxxxxxxxxxxxxxxxxxx Fedora Code of Conduct: https://docs.fedoraproject.org/en-US/project/code-of-conduct/ List Guidelines: https://fedoraproject.org/wiki/Mailing_list_guidelines List Archives: https://lists.fedoraproject.org/archives/list/users@xxxxxxxxxxxxxxxxxxxxxxx
