These are patches designed to improve system responsiveness and interactivity with specific emphasis on the desktop, but suitable to any workload. Apply to 2.6.36: http://www.kernel.org/pub/linux/kernel/people/ck/patches/... Broken out tarball: http://www.kernel.org/pub/linux/kernel/people/ck/patches/... Discrete patches: http://www.kernel.org/pub/linux/kernel/people/ck/patches/... All -ck patches: http://www.kernel.org/pub/linux/kernel/people/ck/patches/ Web: http://kernel.kolivas.org Code blog when I feel like it: http://ck-hack.blogspot.com/ Each discrete patch contains a brief description of what it does at the top of the patch itself. The most significant change is an updated BFS cpu scheduler to BFS 357 (Magnum). It should pretty much behave like the older one, but is tighter with respect to keeping to its deadlines, and will continue to behave fairly when load is more than 8 * number of CPUs. The other addition is to decrease the default dirty_ratio. The rest is a resync only since 2.6.35-ck1. Patch series: 2.6.36-sched-bfs-357.patch sched-add-above-background-load-function.patch mm-make_swappiness_really_mean_it.patch mm-zero_swappiness.patch mm-enable_swaptoken_only_when_swap_full.patch mm-drop_swap_cache_aggressively.patch mm-kswapd_inherit_prio-1.patch mm-background_scan.patch mm-idleprio_prio-1.patch mm-lru_cache_add_lru_tail.patch mm-decrease_default_dirty_ratio.patch kconfig-expose_vmsplit_option.patch hz-default_1000.patch hz-no_default_250.patch hz-raise_max.patch preempt-desktop-tune.patch cpufreq-bfs_tweaks.patch ck1-version.patch Those following the development of the patches for interactivity at massive load, I have COMPLETELY DROPPED them as they introduce regressions at normal workloads, and I cannot under any circumstances approve changes to improve behaviour at ridiculous workloads which affect regular ones. I still see precisely zero point at optimising for absurd workloads. Proving how many un-niced jobs you can throw at your kernel compiles is not a measure of one's prowess. It is just a mindless test.
