Here is a short description of pigz:
pigz, which stands for parallel implementation of gzip,
is a fully functional replacement for gzip that exploits
multiple processors and multiple cores to the hilt when compressing data.
And for the installation:
sudo yum install pigz
With pigz, if you don’t have many things running on your multi processor machine then you will see a significant improvement when you are gzipping the files.
