A big part of that reason is that when you attach any library, be it
the SDK or an external SWC, as a RSL, it is going to increase the size
of a singular app. The reason is that when a library is specified as
an RSL, the ENTIRE library gets loaded, not just the parts that are
needed, since it doesn't know what classes will be needed.
Additionally, RSLs are all loaded at Frame 1, and are mandatory
(meaning all RSLs are required to be loaded), increasing the load time
if they haven't been downloaded previously.
Where you see the major gains with RSLs is when you are using them
across multiple applications, because rather than re-download the RSL,
it will pull the RSL from the browser cache, speeding the load time,
although it is still loading more classes than otherwise. For this
reason RSLs are usually a bad idea for a single application, because
it will actually have a smaller size all compiled into a single SWF,
and loading bits of the application via modules, which are only loaded
as needed.

Hi Flexcoders,
It is always claimed that by caching framework.swz of Flex 3, the swf size
is always the smaller. However. from the generated linked-report. in Flex 3,
some classes like RSLloader and some ResourceBundle classes are being added,
which actually increase the swf size.
Since my application is making up of first loading a shared library, and
then upon runtime, it loaded other very small modules. These modules are
making up of very small file size (a few k byte), the overhead added by
these Flex3 loaders and bundles has largly increase the TOTAL application
size by a huge amount (cause there are hundreds of this kind of small
modules when summing up the little increase of this overhead, it becomes M
byte). The start up time is down a bit (loading the smaller library and
smaller init app), but the overall brandwidth consumpt much more now.
So is there any way to trim off those overhead? Or I need to compile those
smaller modules by a Flex 2 compiler?
Anyone have any idea?
