Windows XP Page File
Windows XP uses the paging file is set by the system. Page file is a backup of RAM memory where the operating system stores data temporarily. At the present time the operating system, including Windows, the application process and system using virtual memory which is considered as a RAM. Only the core of the operating system kernel that uses the physical memory directly. That is, virtual memory or page file is always used, even if the memory needed by the whole process that is running far smaller than the main memory (RAM) is embedded in the motherboard.

By default, Windows XP will automatically set the amount of page file size to the following based on the amount of RAM that is connected to the system:

Less than 1GB of RAM
- Initial size (MB): 1.5 x the amount of RAM in the system.
- Maximum (MB): 3x the amount of RAM installed. Operating system 32-bit page file has a maximum limit of 4GB.
1GB of RAM or more
- Initial size (MB): 1x the amount of RAM in the system.
- Maximum (MB): 3x the amount of RAM installed. Operating system 32-bit page file has a maximum limit of 4GB.
Page file will not grow large if you set its initial size to a sufficient size. Using the automatic option for page file will also avoid or minimize the emergence of an error message “Out of Memory” when running many applications or opening a lot of data.

Provide initial size is too large does not also give a negative impact on the system unless the waste hard disk space if not used, and no relation to the performance. Then, how to know whether the RAM is enough or not?

How if computer actives for several hours without a restart. After that see in the Task Manager, particularly in the Performance tab. If the Commit Charge - Peak larger than Physical Memory - Total, the system you need additional RAM. But if you use the option besarannya the page file is created automatically by the system, and Windows XP will automatically enlarge the page file for you.

The problem is that appears next, the maximum size of page file on the operating system 32-bit is 4GB. What if still not as well? If you have more than one hard disk or partition on the computer, just a second page file on the hard disk is. Windows uses internal algorithm to determine where the page file is used to set the virtual memory optimally.

According to Microsoft, the solution is to create an optimal page file that is stored in the main system partition and create a page file at the partitions in the hard disk or partition that is rarely used.
