Comment 2 Stanislav Aubrecht 2013-05-23 14:27:29 UTC 
Vector.indexOf() takes 7000ms to finish - either too many nodes in Outline model or badly written equals() method.
Please evaluate.
Comment 3 Martin Entlicher 2013-05-24 16:42:35 UTC 
There is no equals() method overridden, therefore the Object.equals() is used.
The list of nodes has to be really large. Only the iteration through them takes 2.5 seconds.
Since the performance of VariableHeightLayoutCache would have to be improved in JDK, it's won't fix from NetBeans side IMHO.
