Speed on i386 shouldn't count that much here.
Big machines run x86_64 and cgroup cpu accounting doesn't make much
sense on old i386 single core machines.
Would still be great to see the first patch go in then.
The idea of splitting was to:
a) show the real change
b) make at least the first go in if the snd does not work out
Thanks,
Thomas
