What should be the effect of size of the time quantum in round robin CPU scheduling?

The size of the time quantum in round robin CPU scheduling significantly affects system performance. A smaller time quantum can lead to improved responsiveness for interactive tasks but may increase context switching overhead, reducing overall CPU efficiency. Conversely, a larger time quantum can decrease context switching and improve throughput, but may lead to longer wait times for shorter tasks, negatively impacting responsiveness. Therefore, choosing an optimal time quantum is crucial for balancing responsiveness and system efficiency.
