Exam Tip For the exam, remember that Task Manager can show real-time information
about the CPU, RAM, and virtual memory, but the measurements are fairly limited. To collect
more detailed information, use the Performance console. The Performance console also
allows you to collect performance data over a longer period.
How to Change the Base Priority of a Running Process
19-5
Page Faults The number of times that data had to be retrieved from the page file
on the hard disk for this process because it had been paged out of
physical memory. Windows XP Professional uses a page file stored
on the hard disk to augment physical memory. When the physical
memory is full, Windows swaps older information in physical memory
to the swap file to make room for newer information. Too many
page faults often indicate that you need more physical memory.
Peak Memory Usage The maximum amount of physical memory resident in a process
since it started.
Thread Count The number of threads running in the process. This column can be
useful for troubleshooting multithreaded applications.
Changing the base priority of a process determines how much processor time Windows
XP Professional devotes to the process compared with other processes. By
default, most processes run at a base priority of Normal. However, you can change the
base priority for a process by using the following steps:
1. In Task Manager, on the Processes tab, click the View menu and then click Select
Columns.
2. In the Select Columns dialog box, select Base Priority and then click OK.
The Base Priority column now appears in the Task Manager window.
3. Right-click the process for which you would like to change the base priority.
4. On the shortcut menu that appears, point to Set Priority, and then select one of the
following commands:
❑ Realtime
❑ High
❑ AboveNormal
❑ Normal
❑ BelowNormal
❑ Low
