The protocol from clients is probably becoming noise. What happens
to a simple XDrawLine request after it gets to the server depends greatly
on the desktop being used. The conventional model was the request
was sent directly to the graphics board and the rendering happened to
the onscreen memory. We are on the cusp of switching to compositing
desktops, so the rendering may now happen to offscreen graphics memory
or even system memory. I believe you will soon find matching hardware
to expected desktop graphics performance depends more heavily on the desktop
being used than the client rendering commands.
