Our collapsed compound nodes contain a lot of sub-nodes, when calling API getAllCollapsedChildrenRecursively, it takes more than 30 seconds to return. The following code (expandCollapseUtilities.getCollapsedChildrenRecursively) inside a For loop is very expensive:

collapsedChildren = collapsedChildren.union(children[i]);

Remove it and do "collapsedChildren = collapsedChildren.union(children);" outside of the loop is much faster
