Question

What are the advantages and disadvantages of each processor having a separate queue and all the processors having a common queue?

Answer 1

.CPU utilization: what percentage of time the CPU is not idle. A good scheduler keeps the CPU busy. In particular this means thatwe want to space processes out so they aren't all trying to do I/O at once.*.Throughput: how many processes are completed per time unit. (Depends on whatthe processes are doing).*.Turnaround time: how long it takes a particular process to finish.*.Waiting time: total time spent by all processes in the ready queue.*.Response time: time between user input and corresponding system action.
