Hi!
PS: I'm using the kernel with Gentoo patchset. But I confirmed the above
persists with the vanilla kernels.
PPS: I also played around with the timer frequency, and premption model.
Would those make a difference to CPU usage?
Yes. Or rather, it will make accounting more accurate, so that you see
that 1% cpu usage, unlike previous kernels where something still ate
cpu but kernel did not know it.
