Description

Discuss how to reduce the cost of paging to disk because frequent paging is prohibitive. Looking back to all discussions on paging, one can surmise that paging is an overhead rather than an advantage and it exists because of the rapidly escalating memory requirements for multi-tasking, multi-user computer system. (Toncich,1994) It will make for system efficiency and improve overall performance, if the effects of paging are reduced. We understand that paging is the cure to external fragmentation but excessive paging can also lead to internal fragmentation. Hence, the need to get the size of paging file right is critical, else the system will have performance issues. (Gardinier,1998) Having smaller page files might force the system to enlarge them intractably in order to compensate for increased paging activity leading to another situation that causes the system to experience excessive page faults. Another possible problem that can arise from all of these is thrashing which causes the system to spend more time paging than executing applications. (Krzyzanowski,2012) In summary, to reduce the cost of paging to disk. Here are the things that can be done: 1. 2. 3. 4.

Upgrade the size of the physical memory (RAM) Don’t make the system responsible for increasing the page file size Monitor system’s changing memory needs and properly configure the paging file Minimize number open windows sitting in the task tray. Else, they will use up memory.

Finally, according to Stephen J, Bigelow (2013), we can employ a simple tactics to improve paging by placing the page file on a local physical disk separate from the OS or workloads.
