DEVICE CENTRAL
User Guide
37
To calibrate the device, the Emulator tab runs a test application and compares the test result with the result stored in
the database, which was obtained by running the same test application on the actual device. Device Central derives
an index number based on the comparison. This enables Device Central to know how much to slow down the
desktop or laptop computer to emulate the device. It also gives Device Central a way to group devices into Perfor-
mance Index categories. The categories let you compare device performance (i.e., a high index number indicates a
high-performing device). Player version, display size, heap size, monitor size, and the computer's memory
consumption all affect the calibration result.
Most of the Performance options, except for Rendering and Calibrate, remain disabled for any device that is not
calibrated. After you perform the first calibration for a device, all performance options are enabled for that device.
To achieve accurate emulation results, perform device calibration frequently because other processes running on
your computer affect performance.
Calibrate a device
1
Open the Emulator tab by doing one of the following:
•
From Adobe Device Central, select File > Open, navigate to a Flash SWF file, and double-click the file.
•
In Flash, open a file and select Control > Test Movie.
2
On the Adobe Device Central Emulator tab, expand the Performance panel.
3
Click Calibrate.
A progress bar appears as the calibration proceeds.
4
To enable all options, select Simulate Performance.
Calibrate a device from the Performance panel.
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.
