Not sure if this will help, but one thing I did soon after I started working with Eclipse was to set a limit on how many editors it kept open at once. I didn't do any precise tests to see if this actually helped reduce memory usage, but based on casual observation, it did seem to.
To do this: - Window > Preferences - General, Editors - Check "Close editors automatically" Then set the other related options as you like -- the values I chose are: - Set "Number of opened editors before closing" to 15 - Under "When all editors are dirty or pinned," check "Open new editor" Mike Morearty, Flex Builder team
