CentOS 7.x parallel command line download

For parallel download in centOS 7.x install aria2 package and use aria2c command as follows:

   yum -y install aria2
   aria2c -x 16 http://centos.excellmedia.net/6/isos/x86_64/CentOS-6.9-x86_64-bin-DVD1.iso

Here, -16 refers to number of parallel threads that should be used for downloading given file / URL.

If the goal is to check bandwidth between two machines then iperf3 has better options to the same without getting into setting up webserver and a large file to download.
