How to Simulate Flash Content Download at Various Connection Speeds
As you develop your project, it is important to know how the end user will experience the content delivery. A person with a slower connection has a completely different experience than someone with a blazing fast internet connection.
Using Flash's Simulate Download feature, you will get a feel for each type of connection.
Open a Flash .fla file that contains several images and symbols.
Publish your swf file by choosing Control > Test Movie (Cmd/Return (PC - Ctrl/Enter).
Within your swf window, choose View > Download Settings.
Choose DSL from the pull-down menu.
Press Cmd/Return (PC - Ctrl/Enter) a second time and your swf file simulates a DSL connection. There may be a slight delay before your images appear.
Try the Other Connection Speeds
In this example we chose DSL. The Simulate Download menu lets you experience several other connection speeds.
When Does the Big One Hit?
Another tool available in the View menu is the Bandwidth Profiler. To access the Bandwidth Profiler, choose View > Bandwidth Profiler (Cmd/b (PC - Ctrl/b)). Simulate your movie download again an notice which frames contain the bottlenecks.
Preloaders are our Friends
With the Simulate Download feature, you can see what your user experience is based on his/her connection speed. Consider using a preloader to let the user know that something is coming so don't go away. for more information, see preloader topics in the Flash ActionScript section of this site.
