How to Use Windows Performance Analyzer (WPA) to Boost PC Speed.
Assuming that you chose to use a file-based trace, start an InSequentialFile trace profile by using the following command. If a problem occurs, an error is reported. For example, starting the same profile twice would result in an error that the session is already running.
Show which InSequentialFile loggers have already started for a specific profile by using the following command. You can use the online forms to ask questions and discuss the tools and analysis techniques with other users.
In order to have access to certain kernel events xperf must be run from an elevated command prompt. To create an elevated command prompt, right-click a command prompt shortcut, and click Run as administrator. For many tasks, you need only a kernel trace for effective analysis. Now that the kernel logger is running and generating events, you can open or run an application, or perform other operations.
As an example, you can open Visual Studio, compile a program, and then close Visual Studio. You can use a command line similar to the following example:. The following command stops the kernel logger, and then merges and saves the data to a file named Trace. Now that you have a trace, you can use Performance Analyzer’s graphical trace views and detailed summary reports to examine it in detail.
The command-line tool, Xperf, is not the graphical tool. Xperf interprets this command line as a request to view the trace with Performance Analyzer. It then forwards the file name to Performance Analyzer that then opens and displays the data in the file. You can run Performance Analyzer directly by using the Xperf view command from the command line or by running Performance Analyzer from the Start menu.
On the Selector tab on the left side of the window, you can select the available charts. The X-axis of all charts represents time. Explanation: A kernel trace is started. The kernel session does not need a session name to be specified because its name is unique.
The groups Base and Network are enabled on the kernel provider. This trace will be collected in a file called Kernel. This trace will be collected in a file called User. Using the following command, the UserTrace session is stopped. The two user-mode providers no longer produce events to this session they might still be generating events to other independent sessions.
