Reducing Initial Startup time in Flex 1.5

Question

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

Answer 1

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
http://www.merhl.com/
). any sample code ?
thanks once again !
