When external SWF files, GIF and XML files, and variables are streamed into a player by using
ActionScript calls such as
stream rate for the main SWF file is reduced based on the reduction of bandwidth caused by the
additional data requests. It's helpful to test your document at each speed and on each computer
that you plan to support. This helps you ensure that the document doesn't overburden the slowest
connection and computer for which it is designed.
You can also generate a report of frames that are slowing playback and then optimize or eliminate
some of the content in those frames. For more information, see
on page 40.
To change the settings for the SWF file created using the Test Movie and Test Scene commands,

represents an individual frame of the document. The size of the bar corresponds to that frame's
size in bytes. The red line beneath the Timeline header indicates whether a given frame streams
in real time with the current modem speed set in the Control menu. If a bar extends above the
red line, the document must wait for that frame to load.
Select View > Simulate Download to turn streaming off or on.
