Adam, does this still happen? I export display and xlib. While it is clearly slower than other non-gnustep apps, I do not experience it "so extreme" as you describe.
I used to experience it that bad on 256 color displays before faster rawing was implemented by some kind soul.

2 points,
- ps ops over network
- a mechanism to cache bitmap in the backend.

i think gnustep should try not to pass the bitmap over network.
a seperated server is required so we can pass only ps ops around.
and bitmap image representation should be cached in -back
some how. may be we can have a special bitmap representation
that allow a mechanism to annouce changes onto the bitmap data
so we can copy neccessary part over network?

When I tried to use the GNUstep application remotely on a diskless X
terminal I noticed that the contents of the windows is drawed very
slowly - pixel by pixel, row by row, so that the whole process of
drawing is clearly visible. The non-GNUstep windows draw fast.

If I try to select a few files in the Viewer (in Icon mode) by enclosing
them in a rectangle (with the mouse) the rectangle resizes unacceptably
slow. Notice that the rectangle in the root window of Window Maker
draws very fast.
