Windows 2000 Configuration and Process Priority

Windows 2000 Professional is configured by default to assign variable, short quanta to applications and to boost applications in the foreground. In contrast, Windows 2000 Server is configured to assign long, fixed quanta without any foreground boost to support the efficiency of background services. You can simulate the behavior of one type of operating system when the other type of system is installed—that is, simulate Windows 2000 Server behavior on a Windows 2000 Professional installation, or vice versa. Figure 7.20 shows the interface that you use for changing application response on an installation of Windows 2000 Server.

To access the Performance Options dialog box

1. In Control Panel, double-click System.
2. Click the Advanced tab, and then click Performance Options.

It is easiest to see a change in thread priority as a result of resetting Performance Options if you shut down and then restart the computer. Changes in quantum type and length are so minute they are often undetectable to the user.
