Bạn có thể nâng cao hiệu suất hệ thống theo nhiều cách. Đầu tiên, nếu máy tính của bạn có nhiều bộ điều khiển đĩa cứng, bạn có thể tạo ra một file phân trang trên một ổ đĩa trên bộ điều khiển mỗi.

Distributing information across multiple paging files improves performance because Windows can read and write from disks on different controllers simultaneously. When attempting to write to the paging file VMM tries to write the page data to the paging file on the controller that is the least busy. Second you can enhance performance by moving the paging file off the drive that contains the Windows XP Professional systemroot folder by default the Windows folder which avoids competition between the various reading and writing requests. If you place a paging file on the Windows XP Professional system partition to facilitate the recovery feature which is discussed in the section entitled How to Configure Startup and Recovery Settings later in this lesson you can still increase performance by creating multiple paging files. Because the VMM alternates write operations between paging files the paging file on the boot partition is accessed less frequently. Third you can enhance system performance by setting the initial size of the paging file to the value displayed in the Virtual Memory dialog box s Maximum Size box which eliminates the time required to enlarge the file from the initial size to the maximum size.
