The XO Numbers were recorded from a fairly inactive state. Wireless was active but there shouldn't have been any traffic. I did launch X with just an xterm, so sugar shouldn't be in play at all. I didn't think of the speed of nand writes however. > 2) The accel path requires reading from video memory (which is > very slow) I'm curious as to why reads from video memory are so slow, On standard video cards it's slow because there is quite a division between the CPU and the video memory, but on the geode isn't the video memory shared in the same SDRAM as Main memory. There's a separate 2 meg for DCON memory, but I was under the impression that was just to remember the last frame. Do I have that all wrong? _______________________________________________ Devel mailing list Devel@lists.laptop.org http://lists.laptop.org/listinfo/devel
