Btw I found it's perfectly fine to simply name this main. In IntelliJ the run button on the class will run this, but the run buttons next to the benchMarkAvgTime and benchMarkThroughput functions still work fine.

MyState myState = new MyState();
myState.setup();

while (true) {
List<SelectedField> selectedFields = new DFSelectionSetBenchmark().getSelectedFields(myState);
Thread.sleep(500);
}
}

}
