How To Profile A Laszlo App in Flash Builder
Obtain the Flash Builder application from Adobe. There is a 60 day trial.
Important: Install the standalone Flash Debug Player (Content Projector) on your system.
[1] Compile the Laszlo app to SWF10
To get the best performance data that matches production use, we want to compile the app without Laszlo debugging, but we need the flex compiler's debug info to be included.
To do this, compile the application to a .swf file, using the following options. This adds flex debug info, but doesn't turn on Laszlo's debug annotations:
lzc --flex-options=debug --runtime=swf10 lpp-9440.lzx
[2] Run Flash Builder (formerly Flex Builder), and select menu item Window -> Perspective -> Flash Profile
See instructions on using the Flash Profiler at http://livedocs.adobe.com/flex/3/html/help.html?content=profiler_3.html
[3] select menu item Profile -> Profile External Application
[4] Click "New...", and browse to add the path of the LPS .swf app file
[5] Double click the app .swf filename to launch app for the profiler
[6] The app should appear in a player window
[7] In the Flash Builder Profile view, you can see a memory profile, and there is also a little clock icon used to capture a performance trace of execution times.
