Increasing Your System’s Performance.
Using performance.
monitor hundreds of different statistics about all areas of the operating system. Similar to other system monitor tools, its purpose is to help you detect problems and improve your system performance.
The easiest way to start the performance application is by the command line or by using the Run command in the Start Menu.To start the performance application:
1. Click the Start Menu and select Run.
2. Then type perfmon.msc in the text box and click the OK button.
An icon for the application can be found in the Administrative Tools folder located in Control Panel. But for most users, running the preceding command will be the easiest method of starting the program.
The Performance application gets the data for its performance counters from the System Registry. If you would like to change the source of the data so that it will get the data directly from the Windows Management Interface instead, simply start the performance counter with the “/sysmon_wmi” flag. Then type perfmon.msc /sysmon_wmi in the text box on the Run dialog box. Once the program is started, you will be greeted with a graph of data as well as a list of activecounters. You will see a graph of the % Processor Time as well as memory Pages/sec and the avg. Disk Queue Length. These are all great stats, but the Performance application has quite a few more from which to choose. In order to add more performance counters, simply click the icon with the _symbol on it or press Ctrl_I and the Add Counters window will appear,
Once the Add Counters window is shown, you will notice where it states “Performance Object.” In the drop-down menu list box below this is a list of all of the possible items that you are able to monitor. Depending on the services that your computer has installed, such as the Web server IIS, you will have more or less items available.Take a few minutes to browse through the list. You will notice that when you select a different item subject, you will be shown a new list of detailed counters in the box below. You have the option to add all counters or you can select only specific counters from the box by pressing the Ctrl key to select multiple items. Additionally, to the right of the listing box is another box which lists the instance of the object you are going to monitor. This gives you the ability to define the scope of the counter so that you can monitor only one specific device instead of monitoring all devices. For example, it is possible to monitor the queue length of just one hard drive instead of the total file access queue length.
Once you are finished selecting all of your counters for a specific object, click the Add button. Once you are finished adding counters for all of the objects you are interested in, click the Close button.
