Is there a way to get it to use more than one core?
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.
Thank you!
I stuck it in my keeper file on the subject
