title: Eclipse Luna excessively slow
body: <p>Kelper was significantly quicker at opening folders with lots of files in them (approx 200 files on average).  Luna on the other hand will spin for about 10 seconds to open each folder.  I have up heapsize and re clone my workspace as to not use any of my old eclipse properties.  I thought this fix the issue it has not.  Does anyone have any other ideas (min heap size 1024, max 2048), ram is not an issue or processing package?</p>
