Ever do something and then wonder why you didn’t do it years ago?
I just updated my Flash Builder 4.5.ini jvm settings to increase allocated memory and found a noticeable improvement, overall, in Flash Builder. I am using the stand-alone installation on Mac, so my .ini file is found by clicking on my Adobe Flash Builder 4.5.app (launcher) file and selecting “Show Package Contents”. The Adobe Flash Builder 4.5.ini file is found in Contents/MacOS/ folder in the launcher. If you are using an Eclipse plugin installation, then it would be the same path from your Eclipse installation.
I have 6GB of RAM on my machine, these settings might be able to be tweaked for even better performance but I am really pleased with the performance increase I’m getting from this configuration:
-nl en_US -startup ../../../eclipse/plugins/org.eclipse.equinox.launcher_1.1.0.v20100507.jar --launcher.library ../../../eclipse/plugins/org.eclipse.equinox.launcher.cocoa.macosx_1.1.1.R36x_v20100810 --launcher.defaultAction openFile -showsplash -vmargs -Xms512m -Xmx1024m -XX:MaxPermSize=512m -XX:PermSize=128m -Xdock:name=Flash Builder -Xdock:icon=../Resources/fb_app.icns -XstartOnFirstThread -Dorg.eclipse.swt.internal.carbon.smallFonts -Declipse.product=com.adobe.flexbuilder.standalone.producte36 -Declipse.application=com.adobe.flexbuilder.standalone.FlashBuilderApplication
Basically, I simply doubled all memory settings. Improvements were immediate and noticeable upon restart.
