Yes, probably specific cell renderers would help. You also have to keep
an eye open to avoid inefficient default ways of the GtkTreeView, like
sorting the treeview when each element is added instead of doing a
single bulk sort, or rendering each row when added instead of loop
rendering. Anyways, the xffm treeview is faster than the nautilus
equivalent (showing everything), and Rox does not have a treeview, just
a listview, so there is no comparison.
