The Performance Analysis Tool application operates in two different modes, the Performance Analysis Tool user interface is similar in these two modes.
- Offline mode
In offline mode, you can use the Performance Analysis Tool to analyze performance data files locally. This enables you to view the properties of the OpenGL ES graphics without direct access to the target hardware platform.
You can load multiple performance data files at a time.
See Using the Performance Analysis Tool in offline mode for more information about using offline mode.
- Online mode
In online mode you can connect to a target hardware platform and analyze graphics applications running on the target. The Performance Analysis Tool uses a network connection to connect to the target platform.
You can connect to one online data source at a time.
Online mode is only available when you connect to a hardware platform and not when using with an OpenGL ES 1.1 or 2.0 Emulator.
See Using the Performance Analysis Tool in online mode for more information about using online mode.
You can connect to one online data source and load multiple performance data files simultaneously. This assists you in application optimization because it enables you compare multiple runs of an application.
