The first thing I'd try to change is the model itself... do you use the
standard TreeStore, or did you derive an own class from TreeModel?

Second, did you already try to put the update of the model into an own
thread? As you describe it, the TreeView seems to be notified a few
hundred times per second of an update. Maybe you can write a thread
that polls for new data every second or so, and updates the TreeView
only after every poll.

Hope this helps,
