Looking at the code, be aware this is going to give incorrect results/suggestions for certain stats it generates when multiple jobs are running.  

It also seems to lack "the algorithm should be rewritten" and "the data was loaded incorrectly" suggestions, which is usually the proper answer for perf problems 80% of the time.
