After your benchmark
Once you have done your benchmark, you should have a database of your runs (the folder we talked about earlier with the reports, configuration, and so on). Now, to ensure you did the benchmark for a reason, there are few actions you should take.
Note
In this section, we assume that you will do these steps after the benchmark, but you can do them during the benchmark itself. It is presented this way because it is something you can do offline, and if you have some costs associated with the benchmark, these are tasks you can postpone easily.
Writing a report
Normally, at this point, you have collected all the data corresponding to the hard work you did during the benchmark. It is quite important to aggregate this in a report. The report will mainly explain the investigation (why you changed some settings and so on) and expose the results of the runs.
You can, of course, ignore the useless runs (no significant change in the performance), but it is always interesting to integrate...
