libglade vs glade for dialog generation

[Hazael Maldonado Torres <gtk-development itxolutions com>]

Hi folks

I have been using Gtk for some months with glade for GUI development. So 
far I only use the code generation option of glade but I saw that some 
application such as gnumeric only use the xml file generated by glade 
(import.glade) and then they load that file at running time using libglade.

The question is simple, Which way is the best? I will develop and 
application which will have more than 20 dialogs therefore i am 
interested to know which approach will give the application better 
performance.

Thanks in advance for any comments.
