--------------
Parallel DD performance:
* Copy the local-script.sh in ${mountpoint}/benchmark/ directory
* Edit it so the blocksize and count are as per the requirements
* Edit the launch-script.sh script to make sure paths, mountpoints etc are
alright.
* run 'lauch-script.sh'
* after the run, you can get the aggregated result by adding all the 3rd entry
in output.$(hostname) entries in 'output/' directory.
