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 2.6.13
or server version
Split patches available.
Setting HZ to 250 gives you the worst of both 100 and 1000 without any
advantage from either. Furthermore there are performance issues with dvd
burning (it seems) and unresolved issues with -ck, so this patch removes the
option entirely to force 100 or 1000.
A bug in the background scanning patch meant that if you had no highmem
enabled it would keep intermittently scanning indefinitely even if all memory
is balanced, slowly trashing cached ram.
Swap prefetch code was deciding to do prefetching based on overall free
memory. This update makes it check every memory zone to ensure they all have
free memory before doing any prefetching.
