Comment 2 Tomas Pavek 2010-01-27 08:15:00 UTC 
80% of time spent in font initialization done by JDK, provoked by innocent call of JLabel.getMinimumSize() calling getFontMetrics. It takes more than 8 seconds - but we can't do anything about that. This kind of initialization should happen just once and it's strange the GUI builder would be the first place this is called.

I have no explanation for such long time - other than that the whole system was overloaded and slow at that moment (the snapshot statistics indicate that).
