Consider a process experiencing a large number of page faults. Describe the effect, if any, of increasing this process’s scheduling priority.
What will be an ideal response?
A process experiencing a large number of page faults becomes I/O bound as the system
loads its pages into memory. Increasing this process’s priority enables it to issue I/O
requests for pages at the earliest possible moment but does not necessarily decrease the number
of page faults it will experience. If the process is thrashing, it requires additional page
frames, not processor time, to execute efficiently.
