	Actually the low level rendering code in the xnews server is horrid. It
is the prime reason we don't see better performance in OpenWindows. The 
NeWS interpreter was completely re-written for V3 and though they sped the
interpreter up quite a bit there was basically *no* performance boost because
of the rendering code.

I think if keith packard worked for SunSoft and wrote new rendering code
for the xnews server you would see almost no difference in "vanilla" MIT
servers and the xnews one.

That is not to say that there  aren't other areas that could be sped up.
