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 184.108.40.206):
or for server version:
Split patches available.
Changes since 2.6.12-ck3:
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 :)
+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.
Latest stable version.
