JavaFX Performance with Debugger attached

When I debug my JavaFX application in NetBeans it runs very slow, orders of
magnitude slower than normal.  Swing apps on the same configuration do not
have the same problem.

My guess is that adding and removing Nodes from the Scene is much slower in
this case, since not all operations are affected.

For example, I have a TreeView that is filtered on-the-fly as I type in a
search field.  It updates as fast as I can type normally, but under the
debugger each keypress takes a full second or so to appear.

Has anyone else noticed this phenomenon?
