GNOME via remote X server - slow root window redraw

Hi.

I though I might forward a question of mine that got no response on the 
mailing list:

Actually, the problem could be that the connection just isn't fast 
enough for smooth image data display; I'm using an 11Mb wireless link, 
which I now think is quite a bit slower in real terms even than 10Mb UTP 
Ethernet. However, the operation is just as slow with a plain-colour 
background as it is when using an image. Does this mean that raw pixel 
data is sent to the display even in the former mode? Why?
