It can be added that xz has a lot of useful options, which we can adjust the compression to the capabilities of the equipment (on which we work) while maintaining the maximum possible efficiency and speed of compression.

For example, you can set the compression level, the amount of maximum RAM consumption, and the number of processor threads that can be used. An example of such a command is below:

# xz -k -8e -M 7000MB -T 8 -v files-or-dirs-to-compress.tar

where:

• -k – compress
• -8e – compression level
• -M – RAM usage limit (in GB)
• -T – number of processor threads used
