Test content performance

To tune your content file for maximum performance, adjust any combination of speed, rendering quality, and memory use before you run the emulation.

  1. Select a device that you have calibrated.
  2. If memory is a factor, open the Memory panel, click Edit, and change the value for Static Heap, Dynamic Heap, or both.

    You can enter values higher or lower than the default. You might set the static heap value, which is guaranteed, to a value higher than the default. This setting allows you to downsize the application, step by step, until it meets the device constraints. You can reduce the dynamic heap size to emulate cases where other processes on the device could consume the dynamic memory.

    Change static and dynamic heap size from the Memory panel

  3. Select Simulate Performance.
  4. If execution speed is a factor, adjust the speed. On the Performance panel, move the Speed slider to the right or left, to increase or decrease the execution speed. The default application execution speed is 100%, which is relative to the performance category as defined in the database.
    Note: The slider position is saved on a per-device basis.
  5. If rendering quality is a factor, adjust the rendering quality. The default is Medium. Increasing quality results in better visual appearance, but usually at the cost of a slower refresh rate (performance).

    If the application uses enough memory to exceed either heap size you specified on the memory panel, the player stops, but the frame at which the player stopped remains displayed to show you where the high memory usage occurred. The Output window appears with an Out Of Memory error.

  6. To show performance on the selected mobile device (not your computer), click Emulate Performance.
    Note: The category listed on the Performance panel is derived from the calibration process and is the way that Adobe groups devices based on performance. Comparing the categories of different mobile devices shows which are higher performing devices.
