[comp.windows.x] X11 quite slower than X10 son SUN3-110C/60C ?

Francois.Bitz@SAM.CS.CMU.EDU (08/11/88)

I have a fairly large  appliction which I translated from X10 to X11 
for displaying text,lines, images... on the screen.

On a  BWhite SUN (3-160), X11 is quite the same  (or better) than X10.
However when I run it on a SUN3(110C and 60C)  with a cgfour display 
my appliction runs about 3 times SLOWER than it used too with X10
, especially when displaying  images, filling up rectangles, text,...
Note that this also happens when I am using the BW display (2 planes)
on a cgfour driver. 

	I know for a fact that our version of X11 was compiled with
the standard C compiler. I remember reading on the xpert bulletin 
board that X11 performance could be improved drastically by compiling it
with another compiler.
	Is this true, and if so could you send me a pointer where I can 
dounload an optimized version of X11 binaries and libraries for SUN3s?

thanks
