Timeslice == maximum amount of uninterrupted time given to a task
=> time quantum
Task may run less than timeslice time
balance benefits and overheads
– for I/O-bound tasks
– For CPU-bound tasks
CPU bound tasks
-2tasks, exec time = IOs
-ctx switch time = 0.1s
ts=1s, ts=5s
CPU bound tasks prefer longer timeslices
-> limits context switching overheads
-> keeps CPU utilization and throughput high
I/O bound tasks prefer shorter timeslices
