Consider a demand-paging system with the following time-measured utilizations: CPU utilization: 10%, Paging disk: 98%, Other I/O devices: 5%. What does this imply? How to improve CPU utilization (Think about both hardware solutions and software solutions). Explain why. List at least 3 possible solutions.
