Yes, but I’m asking you to use pbzip. bzip at best utilizes one core, both for packing and unpacking. pbzip uses as many cores as IO bandwith allows - with standard SATA SSDs that’s typically around 30.
pbzip can only utilize multiple cores if the archive was created with it as well.
I’ve searched for it and xz also doesn’t use multithreading by default, you can change the program tar uses to compress by passing the -I option. For xz using all possible CPU threads:
tar -cv -I 'xz -6 -T0' -f archive.tar.xz[list of directories]
The number indicates the compression ratio, the higher the number, the more compressed the archive will be but it will cost more in terms of memory and processing time

Does something similar happen using

Thanks for answering your own question, this is useful information.
