speeding up GtkTreeView?

[Joop Stakenborg <pa3aba xs4all nl>]

I have done a comparison between the deprecated GtkCList widget and the
new GtkTreeView in gtk+-2.0. Loading 10.000 rows consisting of 3 columns
each takes 0.3 seconds with GtkClist and 4.8 second with GtkTreeView.

I have tried setting the column width to FIXED and have also tried using
gtk_cell_renderer_text_set_fixed_height_from_font(), both with no speed
improvements.

How do I improve the speed of GtkTreeView?

Thanks,
Joop
