Were you thinking that GTKAgg should be as fast or faster than GTK? 

In the past I think GTKAgg and GTK would do dynamic plots at about the
same speed. GTK used to allocate a new gtk.gdk.Pixmap and a new
RendererGTK for every figure draw operation, which was inefficient. I
updated the code so GTK now creates just one RendererGTK and just one
Pixmap (as long as its size does not increase). This should have made
GTK dynamic plotting faster (I didn't benchmark the changes so I don't
know for sure).

Its possible that similar changes for GTKAgg (or TkAgg or WX) would
speed up their dynamic plotting.
