While it may be worthwhile to improve the scheduler, it's clear that there isn't going to be a trivial "fix" for this issue, especially since it's not even clear that anything is really broken. Independent of the scheduler work, it would be very useful to have a pipe benchmark which at least made the dependencies on the scheduler obvious. So I think improving the scheduler and improving the LMbench pipe benchmark are entirely complementary. --david - 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/ | ||||||||||||
