Player attempts to meet the frame rate you set; the actual frame
rate during playback can vary on different computers. If a document
that is downloading reaches a particular frame before the frame’s
required data is downloaded, the document pauses until the data
To view downloading performance graphically, use
the Bandwidth Profiler, which shows how much data is sent for each
frame according to the modem speed you specify.
note: (Flash Professional
CC only) Bandwidth Profiler is unavailable with Flash Professional
CC. You can choose to use Adobe Scout with Flash Professional, instead. See Using Adobe Scout with Flash Professional for
In simulating the downloading speed, Flash Professional uses estimates of typical Internet
performance, not the exact modem speed. For example, if you select
to simulate a modem speed of 28.8 Kbps, Flash Professional sets
the actual rate to 2.3 Kbps to reflect typical Internet performance.
The profiler also compensates for the added compression support
for SWF files, which reduces the file size and improves streaming
When external SWF files, GIF and XML files, and
variables are streamed into a player by using ActionScript calls
such as loadMovie and getUrl,
the data flows at the rate set for streaming. The stream rate for
the main SWF file is reduced based on the reduction of bandwidth
that the additional data requests cause. Test your document at each
speed and on each computer that you plan to support to 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.
To change the settings
for the SWF file created using the Test Movie and Test Scene commands,
use File > Publish Settings.
