Factors Affecting Round Robin Scheduling

Q6. What are the factors that affect Round Robin Scheduling Algorithm?

Ans. Round Robin Scheduling is preemptive (at the end of time slice) therefore it is effective in time sharing environments in which the system needs to guarantee reasonable response times for interactive users.

The most interesting issue with round robin scheme is the length of the quantum. Setting the quantum too short causes too many context switches and lower the CPU efficiency. On the other hand, setting the quantum too long may cause poor response time and approximates First Come First Served (FCFS).
