These are patches designed to improve system responsiveness and interactivity. It is configurable to any workload but the default ck* patch is aimed at the desktop and ck*-server is available with more emphasis on serverspace. Apply to 2.6.12 (This includes all patches in 2.6.12.3): http://ck.kolivas.org/patches/2.6/2.6.12/2.6.12-ck4/patch... or for server version: http://ck.kolivas.org/patches/2.6/2.6.12/2.6.12-ck4/patch... web: http://kernel.kolivas.org all patches: http://ck.kolivas.org/patches/ Split patches available. Changes since 2.6.12-ck3: Added: +s11.3_s11.4.diff Staircase cpu scheduler update. Change rr intervals to 5ms minimum. With interbench I can confidently say there is objective evidence of interactive improvement in the human perceptible range with this change :) HZ-864.diff +My take on the never ending config HZ debate. Apart from the number not being pleasing on the eyes, a HZ value that isn't a multiple of 10 is perfectly valid. Setting HZ to 864 gives us very similar low latency performance to a 1000HZ kernel, decreases overhead ever so slightly, and minimises clock drift substantially. The -server patch uses HZ=82 for similar reasons, with the emphasis on throughput rather than low latency. Madness? Probably, but then I can't see any valid argument against using these values. Changed: -patch-2.6.12.2 +patch-2.6.12.3 Latest stable version. -2612ck3-version.diff +2612ck4-version.diff Version. Cheers, Con
