Hank,
First off the size of your app seems rather large. Here are a few things to
check...
1. @Embed with Images - Embedding images directly adds to file size. Optimize
images before embedding them.
2. Font usage - Fonts embed all glyths into the SWF resulting in a larger files
in jumps of 30K.
Use of Runtime Shared Libraries:
Typically you do not have one Flex app, you have several, and then they start
to multiply. RSL's allow you to package a set of components and assets into a
dll of sorts and reuse it across applications. The result is a single RSL
reused by many smaller Flex applications. The RSL is loaded via URL and cached
in the browser (make sure it gets cached!!) and much smaller flex apps load
this RSL at runtime.
No RSL:
App1.swf = 300K
App2.swf = 300K
App3.swf = 300K
RSL Usage:
App1.swf = 20K
App2.swf = 20K
App3.swf = 20K
Rsl.swf = 280K

Subject: [flexcoders] app startup / load times
For the first time since I started playing with flex (a couple of
weeks) I checked out the size of my app, which is currently 477k.
My app isnt that big, so I presume most of that is just the size of
the framework. I am just wondering what do people think about that in
terms of user start up time. For a user with a 500kbps connection that
is about 8 seconds before the app is loaded. Are people doing loaders
to get things started? is there an accepted strategy for how to deal
with this?
There was another thread recently about how people shouldnt use flex
for websites and one person provided aesthetic reasons. In my mind, if
there is a reason (and I am not arguing that there is) but if there is
a reason not to use it for websites it would be the file size. 10
seconds seems like a long time to make someone wait before they see
something. On the other hand perhaps I am underestimating the average
connection speed.
Anyway, like I said I would just like to get peoples thoughts on this issue.
Hank
