Reducing Initial Startup time in Flex 1.5

[MShehzad]

How can we reduce initial startup time of a flex application ? Suppose we have
a large application , and we want to reduce application startup time. Is it
possible that we are able to devide application into multiple SWF files and
(Initially ) only those SWF files are downloaded on client which are initialy
required ? How can we acheive this i.e architecting application in such a way
that intialy some SWF ( only required on client side ) are downloaded on
client and remaing are downloaded only when they are actually required by
client ?
any help would be appreciated !!!!!!!!!!
thanks

Hi,

Yes it is possible to divide the application into multiple SWFs. You can have
a main SWF file which loads other SWFs when they are required.

You can use the SWFLoader (mx.controls.SWFLoader) component to load a SWF
from within the main Flex Application.

In 1.5 it is mx:Loader.

Also, build the app using containers that support deferred instantiation.
These include ViewStack, Accordion, and tabNavigator. Be sure you do NOT set
creationPolicy="all" this will defeat the purpose.

Also here is a link to an article on improving performance in 1.5:

Thanx for your reply !
yes i want to create similar look.I have two questions regarding this

1) I have little idea that we can acheive such look by using creationPolicy =
"queued" , my question is ..........suppose we are using a tabNavigator with
4 tabs and in each tab we have set creationPolicy="queued" . we are using mxml
custom components of each size 20 Kbs. First time either only first view will
be loaded on the client side(size 20 K) or all 4 views(size 80 K) will be
loaded. It is really important becuase I want to reduce initial startup time.

2) How we can use such component which show size of contents downloaded ( as
used at [url]http://www.merhl.com/[/url]
). any sample code ?

thanks once again !
