Comment 2 Jaroslav Tulach 2010-03-11 03:59:45 UTC 
The PackageView.findNonExcludedPackages shall be called outside of AWT as it can be quite expensive. Does 66s qualify for P2?
Comment 3 David Strupl 2010-03-11 10:13:55 UTC 
All the time is spent in native IO operations. I agree that those should not be done in AWT thread. I am not sure whether the busy cursor will satisfy Stefan but I don't know any better solution for this.
Comment 4 Jaroslav Tulach 2010-03-11 11:12:53 UTC 
You can show "Computing..." in the UI, disable the widget, switch the computation to another thread and when done, return to AWT and fill the UI.
