Wow, thanks for your advances, then i would like to ask, by replacing these 
class, how can i at the same time make use of the framework.swz to compile 
those small modules swf? As there may be case which Main App may not include 
all the class in framework.swc and thus in link-report does not include those 
class. Then the use of an modified SDK unsigned framework.swc means removed the 
ability to cached signed framework class. Or actually, during compilation of 
these small swfs, I should use load-extern for the modified SDK framework?

RE: [flexcoders] Re: Horrible... 3 seconds initialization time for the first frame? Frustrated....

[Alex Harui]

You can fake a link-report or use compiler options to exclude any class you 
want.

In Flex3 ResourceMgr is baked into frame1 so it will be linked in.  In Flex4 it 
wont.  If you're not shipping until after October or so, you might want to move 
to Flex 4.

One more question, the ResourceManager are new element in Flex3, what if we 
don't want that (we have our own language bundle) can we removed that? As from 
the rpt file, there are so many new classes introduced in Flex 3, is there any 
compilation arguement have to be set, from livedocs, it seems even we set the 
language to null, by default it set as us_en.

Re: [flexcoders] Re: Horrible... 3 seconds initialization time for the first frame? Frustrated....

[Anatole Tartakovsky]

Dan,   The classes explicitly referenced in SystemManager are always linked
in the first frame. That said, given the fact that you have open source SDK,
you can play quite a few tricks on Flex/linker.
First, if you are loading in the application domain you can place your own
SystemManager of ~0 size with no references in your modules code hence
removing all the baggage you are complaining about.
Second, on
RSLItem and more importantly on RSLItemsLoader classes - you can
implement modifications in the source code to minimize number of
server requests for RSLs already loaded, do multistreaming in some
cases and customize loading process in runtime to your liking.
You are on open source platform - anything goes.

I believe some of these tricks are documented in application performance
chapter in our upcoming flex book from oreilly - should be out soon.

Hi Alex,

Thanks, then my question is, can the classes in Frame1 of a Module be offloaded 
to RSL or by Link-Report? 

My applications are using nearlly hundred of Module, maybe due to what you 
mentioned about Frame1 class cannot be offloaded, Flex 3 has much more classes 
in Frame1 then in Flex 2. In Flex 2, some of the Modules of my application has 
only a few bytes, but in Flex 3, they become 4 TIME LARGER!!! 

So, even a Module Frame1 code cannot be offLoaded? (These classes should be in 
the application already...) That is quite a bad news, as the total Modules size 
of the application now has nearlly DOUBLE for nothing...

Any good suggestion?

Regards
Dan

RE: [flexcoders] Re: Horrible... 3 seconds initialization time for the first frame? Frustrated....

[Alex Harui]

What goes on in server communications is not my area.  Try posting again with 
RPC or AMF in the subject.  It might then get read by those experts.

I thought utility.swc got folded into framework.swc as well.  Flex.swc is for 
folks not using the UI framework.

Any classes used in Frame1 cannot be offloaded to the RSL.  We did some 
refactoring in Flex4 so more classes can get offloaded to the RSL.

Anything you don't need at startup should be in a module that gets loaded later.

Hi,

First of all, thanks for your response!
Thanks for reminding about the progressive download, I think the 3 seconds is 
still to that response time which I mislead by the Charles figure and think 
that it already downloaded.

But there is still one thing that delay the first AMF call. I noticed there is 
an unknown amfsecure (yes, i am using https) call before any amfsecure call 
issue, and it make a one second delay. Is that for estabishing the channel? 
Anyway to improve this?

Cached framework for framework.swz, rpc.swz and datavisualization has been 
used. BTW, why signed library for utility.swc and flex.swc are not available, 
because they are too small???

Last but not least, is it true that , some of the class like RSLItem from 
Adobe, even we use link-report, cannot be removed from a swf? Cause with an 
parent application with hundreds of modules to load, that small amount of 
depulication in modules means a great issue in terms of total bandwitdh cost..

[flexcoders] Re: Horrible... 3 seconds initialization time for the first frame? Frustrated....

[Dan]

Hi,

First of all, thanks for your response!
Thanks for reminding about the progressive download, I think the 3 seconds is 
still to that response time which I mislead by the Charles figure and think 
that it already downloaded.

But there is still one thing that delay the first AMF call. I noticed there is 
an unknown amfsecure (yes, i am using https) call before any amfsecure call 
issue, and it make a one second delay. Is that for estabishing the channel? 
Anyway to improve this?

Cached framework for framework.swz, rpc.swz and datavisualization has been 
used. BTW, why signed library for utility.swc and flex.swc are not available, 
because they are too small???

Last but not least, is it true that , some of the class like RSLItem from 
Adobe, even we use link-report, cannot be removed from a swf? Cause with an 
parent application with hundreds of modules to load, that small amount of 
depulication in modules means a great issue in terms of total bandwitdh cost..

Regards
Dan
