Prefetch task and fix

Prefetch is the process of streaming application blocks in anticipation that those blocks are needed by an application. When you record with prefetch you can launch the application with faster start up times. Only some key blocks of application data from AppWave are necessary for the application to launch and perform basic functions.

When mastering, notice that a task appears at the bottom of the Broadcast page. This task indicates that In order to Record the launch of the application for faster start-up time you need to master the App from the Test tab before broadcasting. Once the launch data was recorded, remastering before broadcast will not remove this information.

There is also an indicator next to the Broadcast step showing that there is a task that needs to be fixed.
