"Rayiner Hashem: What impact does the design of the new server have on performance? The new X server is different from Apple's implementation because the server still does all the drawing, while in Apple's system, the clients draw directly to the window buffers. Do you see this becoming a bottleneck, especially with complex vector graphics like those provided by Cairo? Could this actually be a performance advantage, allowing the X server to take advantage of hardware acceleration in places Apple's implementation can not?"
"Keith Packard: I don't think there's that much fundamental difference between X and the OS X window system. I'm pretty sure OS X rendering is hardware accelerated using a mechanism similar to the DRI. Without that, it would be really slow."
Maybe now you believe me that Apple's system *does* use the hardware accelerator to draw into the window buffers <grin>
