Well, just search the archive of this list (or gtk+'s); I remember some 
emails worrying about performance, especially when it comes to display 
full databases 
(http://mail.gnome.org/archives/gtkmm-list/2003-February/msg00066.html, 
probably 
http://mail.gnome.org/archives/gtkmm-list/2003-October/msg00204.html, 
etc.). On my own case, working on POS systems, showing the whole 
database of items to be sold in a supermarket (>40000) already forced me 
to tweak TreeView to make it usable. Another case is when you need to 
show data quickly, in (more or less) real time situations, when you 
cannot afford losing CPU time just to show a simple item in the screen.
In any case, this discussion seems to be out of topic in a list that's 
about a C++ wrapper of a toolkit that happens to have that famous 
widget; probably it would be healthier in gtk+, where probably I would 
receive the same old answer: "write it yourself if you need it"...
