Best answer 7 votes 7 votes “Waiting time” is one of the metric for deciding the schedule of processes. If the OS tries to minimize the average waiting time of the processes it’ll follow the $\textsf{Shortest Remaining Time First}$ algorithm which though reduces the average waiting time of processes can still cause a long burst time process to $\textsf{starve.}$ Arjun answered May 4, 2021 • selected May 4, 2021 by gatecse Arjun comment Share Follow See all 0 reply Please log in or register to add a comment.
5 votes 5 votes Waiting time is high when a shorter process waits for a longer process to finish(as in FIFO), or a process waits because many shorter processes keep on coming(as in SJF). Overall, such a situation is undesirable. Miny answered Dec 5, 2018 Miny comment Share Follow See all 0 reply Please log in or register to add a comment.
2 votes 2 votes For better perfrmance of the os waiting time should be less of a process.It is undesirable that a process waits to get chance for cpu.

So this could be one undesireable effect. 1 votes 1 votes Please log in or register to add a comment.
