Let's clarify this a bit. The "poorly performing" part refers to the fact that the ddx for that device uses the generic Color Frame Buffer code instead of hardware support, just as the qvss/vs2000 server uses the generic Monochrome Frame Buffer code. Servers based on cfb are slower than ones that use mfb because they have to do a LOT more work (color pixels typically have 4, 8, or many more times the number of bits that monochrome pixels have). It ought to be relatively easy for someone who knows the low-level graphics libraries of the machine to optimize many of the more common operations (solid and tiled filled rectangles, solid text, copy area, lines, etc.). Do I hear any volunteers? Jim Fulton MIT X Consortium
