mxmlc: fitter, happier, more productive Brian Deitte

more productive (with faster compiles)

Tips for Flex Builder 3 • Build every application in one project using multiple source paths • Build parts of the applications as SWCs • Close extra projects • Use a system font instead of embedding fonts • Turn off "Copy non-embedded files to source folder" • Turn off "Build Automatically" • More tips at: http://www.deitte.com/ archives/2008/10/how_do_you_spee.htm

General Flex 3 Speedup • To get a 25% speedup, use pieces of Flex 4: http://www.deitte.com/archives/2008/10/ a_faster_flex_3.htm • Want more of a speedup? Use Flex 4

Tips for Flash Builder 4 • Use the Flex 4 SDK • Use the Flex Builder 3 tips other than using one large project

fitter (with smaller SWFs)

Use You Compiler Options Wisely • Use framework RSL... if at all possible: http://livedocs.adobe.com/flex/3/html/ help.html?content=rsl_09.html • Use conditional compilation... with care: http://livedocs.adobe.com/flex/3/html/ help.html?content=compilers_21.html

Third-party Happiness • Third-party projects can help with smaller SWFs • Tested with 431 KB SWF that uses framework RSL, Cairngorm, and has a lot of embedded images • Also tested with a 254 KB SWF that only uses AS3, architected for size, and has no embedded images

Flash Optimizer • http://www.flashoptimizer.com/ • Using "Good" compression settings: • SWF #1: 17% savings • SWF #2: 0% savings

secureSWF • http://www.kindisoft.com • Using the "Optimize for size" settings: • SWF #1: 4% savings • SWF #2: 5% savings

Apparat Reducer • http://code.google.com/p/apparat/ • At .5 for both settings: • SWF #1: 3% savings • SWF #2: 0% savings

Apparat TAAS • http://code.google.com/p/apparat/ • Look for more details as they show up on http://blog.joa-ebert.com/ • Lots of excitement around the project with many potential compiler optimizations • Based on TODOs in TaasBuilder.java, not usable right now for real SWFs

Flex 4 Changes • Image compression in Embed. To quote: "The fix for SDK-18954 adds Embed support for smoothing, compression and quality. For example: [Embed (source='foo.png', smoothing="false", compression="true", quality="80")] private var bar:Class; smoothing and compression are booleans and quality is a percentage between 0 and 100. quality requires that compression be true. The actual smoothing is implemented by the player at runtime."

Future Changes? • In Alchemy: C to LLVM to AVM2 bytecode • In iPhone kit: AS3 to LLVM to ARM assembly code • In Future: AS3 to LLVM to AVM2 bytecode?
