eclipse performance problems

It seems that eclipse doesn't like running on gcj at all. Changing the default OS virtual machine to Sun's JDK improves performance considerably.

A couple of generic steps to set the default JDK (most distros have their own tool to do that) - make sure 'which java' returns Sun's java executable.

Also, add the path to Sun's libraries at the top in the java_home file in eclipse's directory.

A more complete guide of how to do all this in Ubuntu can be found here: http://ubuntuforums.org/showpost.php?p=1065271&postcount=8
