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.

iozone:

bash# iozone - +m iozone_cluster.config - t 62 - r ${block_size} - s
${file_size} - +n - i 0 - i 1
