Improving Flash Builder’s performance

For those of you who are having performance issues with Flash Builder, it could be that the Java heap-size settings are too low. Here is a quick and easy fix, which should make Flash Builder easier to use. People on Twitter who have tried this modification report better leverage of their hardware and overall improved performance.

For Windows:

  1. Navigate to your FlashBuilder folder – C:\Program Files (x86)\Adobe\Adobe Flash Builder 4.5\
  2. In a text editor, open FlashBuilder.ini (for Windows) and Adobe Flash Builder 4.5.ini within Contents/MacOS/folder (for Mac OSX) .
  3. Find the lines that says “Xms40m” and “Xmx512m” (Please note: the numbers may already be configured).
  4. Replace these two lines with “Xms256m” and “Xmx512m” respectively.
  5.  Save the file and restart FlashBuilder.

For Mac OSX:

  1. Open a Terminal window
  2. Navigate to Applications/Adobe Flash Builder 4.5/Adobe Flash Builder 4.5.app/Contents/MacOS (you may need to enclose these folder names in quotes).
  3. In a text editor, such as vi or emacs, open Adobe Flash Builder 4.5.ini.
  4. Find the lines that says “Xms40m” and “Xmx512m” (Please note: the numbers may already be configured).
  5. Replace these two lines with “Xms256m” and “Xmx512m” respectively.
  6.  Save the file and restart FlashBuilder.

 

Hope that helps,
