The time quantum should be long enough to allow a high percentage of the CPU cycles to run to completion. If the time quantum is too short, the CPU spends more time in context switching than in running processes, which decreases overall system performance. Therefore, selecting a time quantum that allows at least 80% of the CPU cycles to run to completion is a good choice.
