My experience with X11.2 for color Suns (110-c and 60-c) has not been
too good many because it is quite slower than the X10.4 version:

	I am writing 'commercial software' and so far everything
I have moved from X10 to X11 is too slow, at time annoying to use;
especially when it comes to images (my main area of interest) on
color suns (although I get good performance  with BW machines). 
	Unfortunately everybody wants X11 (we were very pleased with
the performance of X10R4 on the same machines)!

I have some questions:
	Is this related to moving from pixrect to cfb in Xsun

	Did anybody at Sun or elsewere encounter the same problem?

	Is there a fixup (or hack) in sight, or should I bypass the
	Xsun implementation and make calls to raster-ops for images. 

	Do other machines (i.e Ardent, SUN4-c) have a better performing
	implemnetation.

thanks for any help on that matter.
