Flex 2 Project in Flex 3 Swf File Size Increase?

[Arty13]

I have imported my Flex 2 Projects into Flex 3, when I compile my code the
resulting swf file is 100-200K larger. Why is that? I thought Flex 3 made
smaller swf files...

Any info would be great, thanks.

Its bigger because of the additional features added in flex 3. The framework
size is bigger in flex 3.

However, you can make use of the framework cache in flex 3 to significantly
reduce the size of your swf. Take a look at

But if I choose to use FlexSDK 2 in the Flex 3 enviroment, should that still increase the resulting swf file?

No that should not increase the swf size.

In that case you should get swf with similar size as with flex 2.0.1.

But are you comparing with Flex 2?

I have both Flex 2 and Flex 3 installed on my Dev Machine, I have imported the
same project into each install of Flex using the SDK 2.0.1 HotFix 3.

If I run (compile) my project in Flex 2 the size is fine (239K), but when I
run(compile) my project in Flex 3 the swf file size is 381K

Thats a huge difference, and I dont know why its so much bigger.

Any ideas?
