It is probably must faster to load the data in a bulk fashion.
SimpleTreeDataModel has a method setData(), documented as:
/**
* Sets the whole data en bulk, or notifies the data model that node
* modifications are complete.
*
* @param nodeArr {Array | null}
* Pass either an Array of node objects, or null.
*
* If non-null, nodeArr is an array of node objects containing the
* entire tree to be displayed. If loading the whole data en bulk in
* this way, it is assumed that the data is correct! No error
checking
* or validation is done. You'd better know what you're doing!
Caveat
* emptor.
*
*
* If nodeArr is null, then this call is a notification that the user
* has completed building or modifying a tree by issuing a series of
* calls to {@link #addBranch} and/or {@link #addLeaf}.
*
*
* @throws {Error} If the parameter has the wrong type.
