In order to get the correct "+" signs in the display, "dtml-tree" performs
very expensive lookups in the Zope hierarchy: usually, your
hiearchy is examined two levels deeper than shown. This often
requires loading of huge amounts of objects.

"dtml-tree" has an option to turn this verification off.
You may then see a "+" sign also there are no relevant children
in the object.

This indicates that huge amounts of objects are loaded from the ZODB.
