The traditional UNIX scheduler is a priority-based round robin scheduler (also called a
multi-level round robin scheduler). How does the scheduler go about favouring I/O bound jobs
over long-running CPU-bound jobs?

Answers

Faith
The traditional UNIX scheduler assigns each process a priority and places them in multiple ready
queues. Priorities increase over time to prevent saturation of low priority processes, boosted based on
the amount (as in lack thereof) of CPU time consumed. I/O bound jobs are favoured, naturally, as they
consume very little CPU time.
