Windows XP Virtual Memory Optimization

Virtual memory is very inconspicuous in Windows XP. Windows XP automatically sets it up when it is installed. Users don't even have to worry about this file. However, virtual memory as a supplement and extension of physical memory plays a decisive role in the stable operation of Windows XP. If it is not well set, it will affect the overall performance of the computer.
What is virtual memory?
Virtual Memory is Windows XP as part of the hard disk space used as memory. Virtual memory is essential even if physical memory is large. Virtual memory on the hard disk is actually a huge file, the file name is PageFile.Sys, usually can not be seen. The resource manager's protection of system files must be turned off to see this file. Virtual memory is sometimes referred to as "page file"; it is from the file name of this file.
Setting up a hard disk
Optimizing virtual memory, why do you want to set up your hard disk? This is because virtual memory files (also known as page files) are stored on the hard disk, and improving the performance of the hard disk can also improve the performance of the memory to some extent.
1. Enable disk write cache
Right click on “My Computer" Select “Properties->Hardware”, open Device Manager to find the hard disk currently in use, click Right click on the mouse and select Properties. In the "Strategy" page of the hard disk properties, open "Enable write caching on disk", as shown in Figure 1.
This option will activate the write cache of the hard disk to improve the read and write speed of the hard disk. However, be aware that after this feature is turned on, if the computer suddenly loses power, it may result in irreparable data loss. It is therefore best to turn this feature back on with a UPS. Of course, if you don't do any important data processing work when you use your computer normally, it doesn't matter if you don't have a UPS. This function will not cause too much damage to the system.
