Here are some explanations/reasons for the menu sluggishness:

1) Every menu item is 3 widgets -- the menuitem, a alignment widget, and a
label widget.  A very useful optimization for menu items would be native
label-only support without the alignment and label widgets.

2) Because of all the widgets involved, a ton GTK signal handlers are
called to show the widget.  I havn't profiled GTK signal emmittion, but my
guess is it's not fast.  There is a proposal in the works which could
speed up GTK signal emittion (and break absolutely every GTK program in
exhistance!).
