Waiting time is the total amount of time a process spends waiting in the ready queue. 

Response time is the time from the arrival of a process until it gets the CPU for the first time. 

Throughput is the number of processes completed per unit time. 

Page-fault rate is mainly a virtual memory performance measure and is not a standard CPU scheduling criterion. 

Note : Other common scheduling criteria include CPU utilization, turnaround time, fairness, and efficiency.
