Professional. Select System Cache if you are using your computer as a server or if the
programs you are running require a large system cache.
Virtual Memory For virtual memory, Windows XP Professional uses a process called
demand paging to exchange data between random access memory (RAM) and paging
files on the hard disk. When you install Windows XP Professional, Setup creates a
virtual-memory paging file, PAGEFILE.SYS, on the partition in which you installed
Windows XP Professional. The default or recommended paging file size for Windows XP
Professional is equal to 1.5 times the total amount of RAM. For best results, never set
the value of the paging file size to less than the recommended amount. Typically, you
can leave the size of the paging file set to the default value and let Windows XP Professional
manage the file size. In some circumstances, such as when you run a large
number of applications simultaneously, you might find it advantageous to use a larger
paging file or multiple paging files.
Exam Tip By default, Windows XP manages the paging file size, but you can designate a
file size for special circumstances. The recommended paging file size is equal to 1.5 times
the total amount of RAM.
To configure the paging file, in the Performance Options dialog box, click the Change
button in the Virtual Memory section. The Virtual Memory dialog box (see Figure 5-10)
identifies the drives in which the paging files reside and allows you to modify the
paging file size for the selected drive.
