Using a generic 6.2 kernel and the X server which shipped with it, and mplayer built with the defaults from ports, I would play a movie from an NFS-mounted disk, with mplayer using roughly 30% of the CPU time and xorg less than 5%. On the very same hardware upgraded to a generic 7.0 kernel and the X server which shipped with it, and mplayer built with the defaults from ports, playing the same movie from the same NFS-mounted disk, mplayer still takes roughly 30% of the CPU, but xorg is taking 35-40% of the CPU! The quality of the playback is noticeably rough. What should I be looking for? The diff between an old Xorg.0.log and a new one is pretty massive. I have an ATI Technologies Inc Rage XL AGP 2X rev 39, Mem @ 0xce000000/24, 0xcfeff000/12, I/O @ 0x8800/8, BIOS @ 0xcfec0000/17 according to the log. Thanks for any assistance you can give me! -- George Mitchell
