RE: [flexcoders] Re: Filesize generated swf's

Make sure that you are not generating profiling or debugging code in your SWF by setting the following to false in Flex-config.xml:
 
        <generate-debug-swfs>false</generate-debug-swfs>
        <generate-profile-swfs>false</generate-profile-swfs>
 
When I turn those on, a tiny app (~128K) gets about 20K larger.

An empty Application tag should come in at about 128Kb.  Not sure why
you got 263Kb.  You sure you didn't have any custom theme attributes
on the application tag?

At any rate, starting from 128K, you'll hit your 150K limit really
quick.  However, I encourage you to consider the following:

1) Broadband is here.  The main reason for a 150K limit is download
time.  More and more people are accessing your site over fast
connections where 150K only represents 1/2 second or less

2) Flex/Flash is streaming media.  The user will see the download
progress bar, which you can customize, very quickly, long before the
app has been fully downloaded over slow links, so you can present
something to the user faster than you could trying to get one 150K
HTML page parsed and rendered

3) Flex is not page-oriented.  Thus once you get the SWF downloaded
you don't have to go back to the server for the next screen full, it
is already there.  This is often much better than having to make the
user wait as you go get the next 150Kb HTML page, and the one after
that.

Flex is a new paradigm.  It will require you to think a little
differently and design your apps differently, but you will probably
find that there's a payback in terms of usability and productivity on
the part of your users that is not achievable in the HTML paradigm.
