Flash Builder 4 Extremely slow under Windows 7 + Java

Hi all,

I've been exeriencing major performance issue with Adobe Flash build 4.6 on windows 7 64 bits

I've had the same issue with Eclipse before and I have used to same "fix" and it worked for me

This is what I have done ;

- I've installed Java 1.5.0_22  (version 5, 32 bits)  (even if it is installed in my "Program Files" directory and not in "Program Files (x86)", it is a 32 bit version)

- I've created this launch batch file :

      set CLASSPATH=.;C:\Program Files\Java\jre1.5.0_22e\lib\ext\QTJava.zip

      set Path=C:\Program Files\Java\jre1.5.0_22\bin;C:\Windows\system32;C:\Windows;C:\Windows\System32\Wbem;

      set QTJAVA=C:\Program Files\Java\jre1.5.0_22\lib\ext\QTJava.zip

       cd "C:\Program Files (x86)\Adobe\Adobe Flash Builder 4.6"

      start /B FlashBuilder.exe

- and I run Flash Builder from this batch file

It doesn't seem to work so fine with java 6 even 32bits... but I didn't do any exaustives tests as I have a working solution.

Flex SDK 4.x.x can be very slow in combination with SVN/CVS. I opened a bug regarding this issue. On how to fix it, see here.

My god, it's too slow. We can hardly to use it.... Our OS is WIN7 and XP. All are very slow...  Hardly to work...

Thanks! The problem was all with embedding fonts. I'll play around with other font embedding options (like, using modules to embed and then load them etc.).

Thank you for your help!

Hello again,

it looks like the problem is temporarily solved.

The reason was in the following CSS part:

@font-face

{

fontFamily: Calibri;

fontWeight: normal;

fontStyle: normal;

src: url("assets/fonts/calibri.ttf");

}

@font-face

{

fontFamily: Calibri;

fontWeight: bold;

fontStyle: normal;

src: url("assets/fonts/calibrib.ttf");

}

@font-face

{

fontFamily: Calibri;

fontWeight: normal;

fontStyle: italic;

src: url("assets/fonts/calibrii.ttf");

}

@font-face

{

fontFamily: Calibri;

fontWeight: bold;

fontStyle: italic;

src: url("assets/fonts/calibriz.ttf");

}

Once I've commented these lines - compilation is taking a few seconds. I'm going to go try fix all other compatibility issues so the project compiles without errors and check if the problem returns. And having this project in my workspace was causing the problems with creation of new projects as well. Looks really weird, but that's how the things are.

Previously this part of code was like

@font-face

{

fontFamily: Calibri;

fontWeight: normal;

fontStyle: normal;

src: local("Calibri");

}

but that's incompatible with the updated SDK version, so I had to change them to the mentioned state. I'll keep testing the Builder behavior with these lines commented and we'll see where it leads.

Btw, do I have some misunderstanding of the SDK 4 concept of dealing with the fonts embedding, or that's just a subject to JIRA issue? =)

Are you using a 64-bit JVM? It sounds like you're running Flash Builder Plug-in, so try this:

1) Close Eclipse

2) Open the eclipse.ini file where your eclipse.exe is located

3) Add a new line after "-vmargs" and on that line type "-d32"

4) Restart Eclipse

A 32-bit JRE is required http://www.adobe.com/products/flex/systemreqs/. "-d32" will force your JVM into a 32-bit mode.

You're likely seeing Design view crash because Flash Player support for 64-bit http://kb2.adobe.com/cps/000/6b3af6c9.html.

Alternatively, you can install a 32-bit JVM and assign that to JAVA_HOME.

Please reply if this solution works for you.
