Yes, I've wondered about something. I measured (with ./demo) the speed
of ggiCopyBox on my X server (XF86_SVGA running on the ViRGE) and on
the kgicon driver. I got the following figures:
xlib: 400 boxes/sex
x: 200 boxes/sec
kgicon (accelerated): 200 boxes/sec
kgicon (unaccelerated): 20 boxes/sec
The only guess I can make it that the access to the card memory must
be much slower (PCI) than that to my main RAM (100MHz SDRAM). (Or does
the x target accelerate CopyBox?)
