Still no good. xine drops frames by kernel's make -j2, xmms skips while bk pull (locally). Updates (after switching desktops in metacity) get delayed for seconds (mozilla window redraws with www.kernel.org on it, for example). Priorities of xine threads were around 15-16, with one of them constantly at 16 (the one with most cpu). gcc/as processes were 20-21. That said, it feels better than before, though. And the last changes in the scheduler seem to reveal more races in applications (a found rxvt not checking for errors reading from pty). -alex - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
