Two improvements have been added to the wspy program:

• Added a -z option that creates a zip archive with data files related to the wspy run
• Added a script that calls gnuplot to plot CPU usage over time.

Below is a short listing showing contents of the zip archive as well as running of the gnuplot script.

One CSV file is created for each CPU showing the /proc/stat line each second. A text file is created for the process tree as well.

Below are some examples of the PNG files showing the plots for this benchmark.
