http://www.kerneltrap.org/~npiggin/2.6.8-rc1-np1/ Now that I finally a highmem system, I've been able to make some progress on the memory management chaneges. Still needs more work though. Feedback would be nice if anyone is testing. Scheduler behaviour is generally pretty good now so I've increased the timeslice size to see how far I can push it. Some workloads really demand small timeslices though, so I've added /proc/sys/kernel/base_timeslice. If you have any problems with the default, please report it to me, and check if lowering this value helps. Things are working alright on my desktop with base_timeslice at 10000 which corresponds to around 15-20 *second* timeslices, however I don't do much fancy, and it does have the problem of a newly forked CPU hog possibly causing a long freeze (fixable by using a smaller value for the first timeslice). The -mm version of my patch also removes that kernel's dried gastropod simulator for 2GB+ systems. - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to firstname.lastname@example.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
