Hi Rahul, When you run full-system, the whole point is that the OS is present. This invariably means that there will be background tasks happening besides what ever benchmark you are running. It’s simply something you have to take into account if you want your experiment to be realistic.

As of now there are total 8 stats in stats.txt. This seems to be confusing to me as I dont know that the stats produced in stats.txt belong to my benchmark run or some other stuff running in the background. Could you please shed some light on this?
