During expose the actual drawing seems to be done. I'm getting a lot of time 
spent in gnome_canvas_group_draw(), which is natural, as all items are part 
of a group and that function draws them all.

I'm hitting a dead end here --- it is the actual drawing which uses the whole 
time and so far I haven't seen any refresh delays etc. that I could blame for 
this. 

I guess reducing the number of items to be drawn is the next logical choice.

Best regards,
