Nice to see there is another user. FOr me, besides, GTK2 is slow too.
Cairo and Art are going to be slow. No work around. Try the faithful 
xlib backend, which I use regularly. It will be faster, since instead 
of shuffling bitmaps, it lets the server do the work, like font 
drawing.
If you disable anti-aliasing and use the fonts available on your local 
machine (or have a font server) the speed increase will be very good. 
GWorkspace is ifne to use, as are text application, as is Gorm or 
ProjectCenter.

One thing will be awful though: scrolling. I think GNUstep is quite 
inefficient there, it makes a LOT of X11 calls, art is less affected 
when it uses xshm. On a slower machine you will see that X11 can 
sometimeseat up to 50% of your CPU for some operations..
