You may use option -0, which compresses about as fast as gzip:

But for compression of large files on multiprocessor machines, plzip can be
much faster than lzip at the cost of a slightly reduced compression ratio.
Using option '-0' with 64 compression threads, plzip may be even faster (515
MB/s) than pigz:

Thanks for these advices. Browsing your website I encountered the tarlz software. Any particular reason you didn’t recommended it?

So you may try a command like

  tar -c foo | plzip -0vvo foo.tar.lz

or with a recent version of GNU tar you can use

  tar -cf foo.tar.lz -I 'plzip -0' foo

Thanks again

Would you happen to know precisely what “recent version” here means? As we try to support all kind of setups, we might not use this option, or do a version check before using it.
