Win xp system virtual memory optimization tutorial

System virtual memory, also known as page file, is part of the hard disk space of Windows XP system. The file name in the system is PageFile.Sys, which cannot be seen under normal state. The optimization of system virtual memory is further optimized in the system. Hard disk, test hard drive performance.

First, hard disk settings

Optimize virtual memory, why do you need to set the 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" to select "Properties - "Hardware", open Device Manager to find the hard disk currently in use, click the mouse Right click on the property. In the <quo;Policy" page of the hard disk properties, open “Enable write caching on disk”.

This option will activate the hard disk's write cache, which will increase 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.

2. Open Ultra MDA in Device Management and select “Basic/Secondary IDE Controller” in IDE ATA/ATAPI Controller, right click and select “Properties” to open “ Advanced settings & rdquo; page. The most important setting item here is “transfer mode”, generally should select “DMA (if available)”.

3. Configuring Recovery Options When a fatal error is encountered during Windows XP, a snapshot of the memory is saved as a file for system debugging. For most normal users, this file is not available. What is useful, but it will affect the performance of virtual memory. So it should be closed.

4. Right click on “My Computer", select “Properties->Advanced", click “Set> ; performance options & rdquo; select “ advanced & rdquo; page. There is a “memory usage” option. If you set it to “system cache”, Windows XP will use about 4MB of physical memory as the cache for reading and writing the hard disk, which can greatly improve the physical memory and virtual memory. The speed of data exchange between. By default, this option is turned off. If your computer has sufficient physical memory, such as 256M or more, it is best to turn this option on. But if physical memory is tight, you should still leave the default options.

Second, the page file settings

Windows XP system set virtual memory is very inconspicuous, Windows XP will automatically set it when installed, users do not have to pay attention. 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. Moreover, it is very easy for the program to run smoothly and report errors.

Third, the size of the page file calculation

For different computers, the size of the page file is different. Regarding the page file size setting, there are two widely spread "Formulas", "Physical Memory X2.5" or "Physical Memory X1.5". These two calculation methods are simple, but not applicable to all computers. The most accurate way to set the page file size is to look at the page file size that the computer actually uses in normal operation.

With the built-in logging function of Windows XP, you can monitor the size of the page file normally used by your computer for the most accurate settings. The steps are as follows. Previous12Next page Total 2 pages
