Linux standard compression commands do not support multi-core. Note how to use pigz to speed up the compression process with multi-core.
rpm -ivh https://dl.fedoraproject.org/pub/epel/epel-release-latest-7.noarch.rpm
yum install pigz
If you add "--use-compress-prog = pigz" to the option, pigz will be used for multi-core compression processing.
tar zcvf [compressed file name].tar.gz --use-compress-prog=pigz [Compression target]
